Question

Lurinda ordered some boxes of greeting cards online. The cost of the cards is $6.50 + $3 where n is the number of boxes ordered and $3 is the shipping and handling charge. How much will Lurnda pay if she orders 8 boxes of cards

Answer 1

$55

Explanation:

Put 8 where n is in the equation and do the arithmetic.

cost = $6.50·n + 3

= $6.50·8 + 3 = $52 + 3

cost = $55
