As a salesperson, you are paid $100 per week plus $3 per sale. This week you want your pay to be at least $160. Write and solve an inequality for the number of sales you need to make.
Responses
A 100 - 3s ≤ 160; s ≤ 20100 - 3s ≤ 160; s ≤ 20
B 100 + 3s ≥ 160; s ≥ 18100 + 3s ≥ 160; s ≥ 18
C 100 - 3s ≤ 160; s ≤ 18100 - 3s ≤ 160; s ≤ 18
D 100 + 3s ≥ 160; s ≥ 20

Answer 1

You are a farmer and want to spend under $35,000 on farm equipment. You need a hay baler that costs $6,250 and several plowing disks cost $2,500 each. Write an inequality that models how many plowing disks could be purchased within your budget. What is the maximum number of plowing disks you can buy?
Responses
A 2,500x + 6,250 < 35,000; 11 plowing disks2,500x + 6,250 < 35,000; 11 plowing disks
B 2,500x + 6,250 ≤ 35,000; 11 plowing disks2,500x + 6,250 ≤ 35,000; 11 plowing disks
C 2,500x + 6,250 < 35,000; 12 plowing disks2,500x + 6,250 < 35,000; 12 plowing disks
D 2,500x + 6,250 ≤ 35,000; 12 plowing disks
