Raza works at a flea market selling sunglasses. He is paid $7.50/h plus a 75¢ commission for every pair of sunglasses he sells. Write an equation to model Raza’s earnings. (1 mark)

Find Raza’s earnings if he sells 25 pairs of sunglasses during a 6-h shift. (2 marks)

How many pairs of sunglasses must he sell to earn $90 in 8 h? (2 marks)

7.50h+0.75s        63.75       30

Step-by-step explanation:

7.50 x how many hours + 0.75 x how many sunglasses he sold

7.50 x 6 + 0.75 x 25= 63.75

7.50x8= 60    0.75x40=30               60+30=90
