Answer:

I haven't done anything like this for many years, but i think the answer is 900

Step-by-step explanation:

5000/ 150 = 33.33333333

33.3333333 X 27 = 900

Again, I haven't done this in forever, but I'm 99% sure it is 900. :)

900 would be the answer because;

27/150= 0.18
so 18% of the 150 people like mustard
then 0.18 x 5000= 900
meaning it’d be estimated around 900

A store is running a "buy 3 get 2 free" promotion on twelve-packs of soda. Each twelve-pack costs $5.49. How much will Peter pay for 25 twelve-packs of soda?

Answers

Answer: $82.35

Step-by-step explanation:

For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.

3/5 = 0.6 or 60%

So, if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.

25 x 0.6 = 15

If you are paying for 15 twelve-packs, and each one is $5.49, then the total would be $82.35.

15 x 5.49 = 82.35

Answer:82.35

Step-by-step explanation:

For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.

3/5 = 60%

if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.

25 x 0.6 = 15

15 twelve-packs, each one is $5.49, then the total would be $82.35.

15 x 5.49 = 82.35

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?

Answers

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y = $551.97 (a)

=================== -

33x = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Ribeye is 18.54 and salmon is 9.78

2. The area of the trapezoid is 3, 584. 88 centimeters square

3. Area = 468, 975 ft²

4. Area = 3682. 04 m²

5. 94, 386. 93 mi²

How to determine the area

The formula used for calculating the area of a trapezoid is expressed as;

A = 1/2h( a + b)

Such that the parameters are given as;

A is the area of the trapezoidh is the height of the trapezoida and b are the side lengths

Substitute the values, we have;

Area = 1/2 × 23. 4(61. 2 × 92)

multiply the values

Area = 1/2 × 23.4(153.2)

multiply the values

Area = 1/2(3584. 88)

Now, divide the values, we get;

Area = 3, 584. 88 centimeters square

3. Area = 1/2 × 555 (463 + 1227)

Add the values

Area = 1/2 × 555(1690)

multiply the values

Area = 468, 975 ft²

4. Area = 1/2 × 63 × (41. 56 + 75.33)

add the values

Area = 1/2 × 63 × (116. 89)

multiply the values

Area = 3682. 04 m²

5. Area = 1/2 × 306. 7 (206. 6 + 408. 9)

Add the values

Area = 94, 386. 93 mi²
