Answer:

(b) $17.94

(c) $23.85

Step-by-step explanation:

First, let us find the new price. A percent, divided by 100, can become a decimal:

6 x .15 = .9

6 + .9 = $6.90

(b) $6.90 x 2.6 = $17.94

    ^ price    ^ pounds

(c)

New price: $6.90 x 3.5 = $44.85

Old price: $6 x 3.5 = $21

New - old: $44.85 - $21 = $23.85

(if you need a, mutiply 6 by 2.6 for an answer of $15.60)

Hope this helps, have a nice day :D

b. 6 + 6 × 0.15 = 6 + 0.9 = 6.90

2.6 × 6.90 = 17.94

Explanation:

Find the new price using the formula retail price = original price + markup. Then find the total cost of buing 2.6 pounds at the new price.

c. 3.5 × 6 = 21

3.5 × 6.90 = 24.15

24.15 - 21 = 3.15

Explanation:

Find the total cost at each price and then subtract.
