Question

Samantha wants to use her savings of $1150 to buy shirts and watches for her family. The total price of the shirts she bought was $84. The watches cost $99 each. What is the maximum number of watches that Samantha can buy with her savings? 8 9 10 11

Answer 1

C. 10

Explanation:

Samantha wants to use her savings of $1150 to buy shirts and watches for her family.

The total price of the shirts she bought was $84.

The watches cost $99 each.

Let she bought x watches

then, 84+99x≤1150

subtracting by 84 on both sides, we get

99x≤1066

dividing both sides by 99, we get

x≤ 10.767

Answer 2

The cost of the shirts is stable, so we can subtract $1150 - $84, which = $1066. Now we want to find how many watches we can buy with $1066, or how many times $99 fits into $1066. So divide 1066 by 99 to get 10.77. You can't buy 77ths of a watch, so round it down to 10 and you have your answer. Samantha can buy 10 watches.
