Mrs. Magee purchased 3 ice cream cones with a $10 bill. Mrs. Magee was given $2.86 in change. What is the price of one ice cream cone?
Answer
5.56
Step-by-step explanation
The price of one ice cream cone is $2.38
The given parameters;
the money given by Mrs Magee for the 3 ice cream cones = $10the change given to Mrs Magee = $2.86The actual amount Mrs Magee purchased the 3 ice cream cones;
Total amount paid = $10 - $2.86 = $7.14
The price of one ice cream cone is calculated as follows;
[tex]Price \ of \ each = \frac{Total \ cost}{total \ number } \\\\Price \ of \ each = \frac{\$7.14}{3} = \$2.38[/tex]
Thus, the price of one ice cream cone is $2.38

Answer:
[tex]\huge\boxed{\sf 22}[/tex]
Step-by-step explanation:
By looking at the line segment, we get to know that:
BD = BC + CD
Given that:
BD = 67
BC = 3x - 2
CD = 4x + 13
Solution:
Put the givens in the above equation made.
67 = 3x - 2 + 4x + 13
67 = 3x + 4x - 2 + 13
67 = 7x + 11
7x = 67 - 11
7x = 56
Divide both sides by 7
x = 56 / 7
x = 8
Now, Finding BC:
= 3x - 2
Put x = 8
= 3(8) - 2
= 24 - 2
= 22

I subtract 14 from a certain number I multiply the result by 3 the final answer is 3 what was the number
Answer:
15.
Step-by-step explanation:
3(x - 14) = 3
3x - 42 = 3
3x = 42 + 3 = 45
x = 15.
Let the number = x
Set up the equation:
3(x-14) = 3
Simplify:
3x -42 = 3
Add 42 to both sides
3x = 45
Divide both sides by3
X = 15
The number is 15
2 similar caps cost as much as 3 similar shirts.
4 such caps and 3 such T-shirts cost $36.60
Find the cost of a cap, and the cost of 3 T-Shirts
Answer:
a=dollars6.10
b=dollars12.20
Step-by-step explanation:
Cap=x T-shirt=y
2x=3y 4x+2y=36.6
4x+ 3y=36.6 x=6.10
a) 4caps: 6.10
b) 3T-Shirt:3y=2x=2×6.10= 12.20
(According to Task)
An equation is formed when two equal expressions. The cost of a cap and the cost of 3 T-Shirts is $18.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the cost of a cap be represented by 'c', while the cost of a t-shirt is represented by t.
Given that 2 similar caps cost as much as 3 similar T-shirts. Therefore, the equation can be written as,
2c = 3t
Solve the equation for c,
c = (3/2)t....... equation 1
Now, it is also given that 4 such caps and 3 such T-shirts cost $36.60. Therefore, the equation can be written as,
4c + 3t = 36
Substitute the value of c from equation 1,
4(3/2)t + 3t = $36
6t + 3t = $36
9t = $36
t = $4
Now, substitute the value of t in the equation to get the value of c,
c = (3/2)t
c = (3/2) × $4
c = $6
Further, the cost of a cap, and the cost of 3 T-Shirts is,
Total Cost = c + 3t
= $6 + 3($4)
= $6 + $12
= $18
Hence, the cost of a cap, and the cost of 3 T-Shirts is $18.

Write 2.71 as a simplified fraction.
Answer:
[tex] \frac{271}{100} [/tex]
Step-by-step explanation:
hopefully it makes sense
:)
The decimal 2.71 can be written as the simplified fraction as 271/100.
What are Fractions?Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.
Here p, called the numerator and q, called the denominator, are real numbers.
The given number is 2.71.
We can write 2.71 as 2.71 / 1, since any number divided by 1 is the number itself.
Multiplying both numerator and denominator of 2.71 / 1 with 100, we get,
(2.71 × 100) / (1 × 100)
= 271/100
This cannot be simplified further since 271 is a prime number.
Hence the simplified fractional form of 2.71 is 271/100.
