Question

Last week Juan worked 20.5 hours. This week he works 1.5 times as many hours as he did last. How many hours does Juan work this week?

Answer 1

30.75 hours

Explanation:

Let

x----> the number of hours worked last week

y ----> the number of hours that Juan work this week

we know that

To find out how many hours does Juan work this week, multiply the number of hours worked last week by 1.5

so

`y=1.5x`

we have

x=20.5 hours

substitute

`y=1.5(20.5)=30.75\ hours`
