Teresa made $176 for 11 hours of work. At the same rate, how many hours would she have to work to make $128?

Answer 1

Let's find Teresa's rate: $176/11 hours = $16 per hour.

To put this in another way, for every hour Teresa works, she will be making $16.

To find out how many hours she has to work to make $128, we multiply this by the rate.

$128 x (1 hour/ $16) = 8 hours.

Teresa has to work eight hours to make $128

Answer 2

Her earnings rate is $176 per 11 hours of work: Let R= that rate, then

R=$176/11 hr=$16/hr

To make $128, let t=the time to make $128 at the same rate

($16/hr) x t=$128

t=$128/($16/hr)=8 hrs

Solution: 8 hrs.
