I’m about to fail math ;(

Question

You need to spend at least $50 in one day to receive a store discount. You have already spent $30. Let s be the amount of money (in dollars) you can now spend to qualify

for the discount. Which inequality and solution represent this situation?

s+30<50; 8 < 20

s+30 ≤ 50; s ≤ 20

s+30> 50; 8 > 20

s+ 30 ≥ 50; 8 ≥ 20

Answer 1

s + 30 > 50

subtract 30 from both sides to get

s > 20 is the solution

at least $20 more must be spent to get the discount

"at least 50" means "greater than or equal to 50"

or s> or = 50 in math symbols

or s > 50

> means > or =
