We know lisa has max $150 to spend and she's willing to spend 14 dollars each on tshirts and 58 on jeans. Therefore, we can formulate this into the following equation:
14t+58 = 150
Solving the equation as so:
14t=92 (isolate the variable)
t=92/14 tshirts
t=6.57 tshirts
Since we cant have 0.57 tshirts:
t≈6 tshirts and lisa will have 8 dollars left in change!

well since the question says she will 'spend the rest on tshirts' we can assume she'll get an exact number of tshirts hence the equality

Yes, she gets an integral number of t-shirts that results in spending AT MOST $150. The answer is an integer; the problem is an inequality problem. Students need to learn the rules for solving an inequality.

David W., you are absolutly correct.

O, PLEASE ! You said, "AT MOST", so it makes sense to use ≤ and solve the inequality. Then, when identifying the largest integer less than or equal to a value, you don't have to consider 0,57 t-shirts.06/11/22
