Question

Samantha wants to use her savings of $1,150 to buy shirts and watches for her family. The total price of the shirts she bought was $84. The watches cost $99 each. Choose the inequality that would be used to solve for the maximum number of watches Samantha can buy with her savings.

Answer 1

in general
savings - expenses ≥ 0
(let's assume money left is non-negative and she's not going into debt over this)

she starts off with 1150 and subtracts 84 for the shirt

1150 - 84

then, if we let x = the number of watches, then 99x is the total expenses from the watches

using the logic that savings - expenses ≥ 0, try to write an appropriate inequality

you may need to do some algebraic re-arranging to match your inequality to one of the answer choices
