James, Priya, and Siobhan work in a grocery store. James makes $8.00 per hour. Priya makes 20% more than James, and Siobhan makes 5% less than Priya. How much does Siobhan make per hour?

Answer 1

p=1.2j= 1.2(8) = 9.6

s= .95p = .95(9.6) = 9.12

James makes $8 per hour

Priya makes $9.60 per hour

= 20% of 8 + 8 = 8/5 + 8 = 1.6+8 = 9.6

Siobhan makes $9.12 per hour

= 5% less than 9.6

= .95 of 9.6 = 9.12

5% of 9.6 = .05(9.6) = .48

9.6-.48 = 9.12
