Bianca bought a pack of rechargeable batteries for
$9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?

Answers

Answer:

$0.71

Step-by-step explanation:

Find the cost with sales tax

9.99(1.03)

= 10.29

Subtract this from 11

11 - 10.29

= 0.71

So, Bianca will get $0.71 back in change

Answer: 0.71 cents

Step-by-step explanation:

9.99x0.03=0.2997

9.99+0.2997=10.2897 rounds to 10.29

Avocado Pickers are paid as shown below. What would be the gross
earnings for a worker that picks 1,108 avocados?
1 - 500 Avocados $0.10 each
501 - 700 Avocados $0.14 each
Over 700 Avocados $0.18 each

Answers

Answer:

The avocado picker earned $151.44.

Step-by-step explanation:

Given that avocado pickers are paid $ 0.10 if they collect from 1 to 500 avocados, $ 0.14 if they collect from 500 to 700 and $ 0.18 if they collect more than 700, to determine what would be the gross earnings for a worker that picks 1,108 avocados, the following calculation must be done:

1,108 - 700 = 408

700 - 500 = 200

500 x 0.10 + 200 x 0.14 + 408 x 0.18 = X

50 + 28 + 73.44 = X

151.44 = X

Therefore, the avocado picker earned $151.44.

Answer:

Step-by-step explanation:

First off we have to find the y-intercept with : b = y-mx

[tex]b=2-(\frac{2}{5})(1)[/tex]

[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]

[tex]b=\frac{8}{5}[/tex]

now we have the point slope form
