Question

If James make $7 per hour and Priya makes 20% more than James and Samantha makes 5% less than Priya how much does Samantha make per hour

Answer 1

Samantha makes $ 7.98 per hour

Explanation:

Amount James makes per hour = $7 per hour

Let Amount priya make in one hour be x , then

Priya makes 20% more than James

x = Amount James makes per hour + 20 % of Amount James makes per hour

x= 7 + 20% of 7

`x = 7 +((20)/(100) * 7)`

`x = 7 +((2)/(10) * 7)`

`x = 7 +(0.2 * 7)`

x = 7 +1.4

x= 8.4

Let amount made by samantha in one hour be y

then

y =Amount priya makes per hour - 5% of Amount priya makes per hour

y = 8.4 - 5% of 8.4

`y  = 8.4 - ((5)/(100) * 8.4)`

`y  = 8.4 - ((1)/(20) * 8.4)`

`y  = 8.4 - (0.05 * 8.4)`

y= 8.4 - 0.42

y = 7.98
