Question

The online price for a box of hair clips is $2.60. For any number of boxes purchased, the cost of shipping is $12. The equation c=2.60b + 12 represents the total cost, c, of ordering b boxes of hair clips. If Mrs. Hilton orders 32 boxes of hair clips, what is the total cost? (6.EE.C.9)

Answer 1

$43.2

Explanation:

Step one:

given data

the total cost function is

c=2.60b + 12

Step two:

Required is c, when b= 12

substitute b=12 we have

c=2.60(12) + 12

c=31.2+ 12

c=43.2

the total cost = $43.2
