Question

4 Tina pet sits to earn extra money. She charges a flat service fee of $20, plus $20 per day. If one of her customers spent less than $180, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting?

Answer 1

let x represent the number of days

20+ 20x< 180 ( to find the answer solve for x)


20+ 20x <180 ( subtract 20 from both sides)
20x < 160 ( divide each side by 20 to get x alone)
x< 8
Tina pet sat for less than 8 days
