How much more does Siobhan make..

Question

James, priya, and siobhan work in a grocery store. James makes $7.00 per hour priya makes 40% more than James and siobhan makes 5% less then priya. How much does siobhan make per hour? 

Answer 1

Use James' pay (j) to calculate Priya's pay (p), which will help calculate Siobhan's pay (s).

 

j, p, and s are your variables. Use those to create equations.

j = $7

p = j + (j*40%) = j + (j*40/100) = 140/100*j

s = p - (p*5%) = p - (p*5/100) = 95/100*p

 

Simplifying, you get:

p = 140/100*j = 140/100*$7 = $9.8

s = 95/100*p = 95/100*$9.8 = $9.31

 

Siobhan makes $9.31 per hour.
