Question

Julie is going to a store to buy vases to use as centerpieces at her party. Small vases cost $2 and large vases cost $4. She needs to buy a minimum of 15 vases, and can spend a maximum of $50.
Which system of linear inequalities represents this situation? Let s represent the number of small vases and l represent the number of large vases.

A
s + l ≥ 15

2s + 4l ≤ 50

B
s + l ≤ 15

2s + 4l ≥ 50

C
s +l ≥ 50

2s + 4l ≤ 15

D
s + l ≥ 15

2s +4l ≥ 50

Answer 1

Short answer: A
D: the second equation is wrong. She wants to be under 50

C: The system is confusing money with the number of vases

B: The answer is wrong. She wants to spend under or equal to 50 not over.
