Question

Sal's job pays $7.50 an hour for the first 8 hours he works a day and 1 1/2 times that amount for each additional hour he works per day. If Sal works 10 hours in a day, how much money does he make? please help anyone

Answer 1

We know that in 8 hours, Sal has $7.50. Then, in 10 hours, Sal will have

$8\times7.50+2\times(1\frac{1}{2})\times7.50$

Now, we must convert the mixed fraction into a simple fraction form:

$1\frac{1}{2}=\frac{2\times1+1}{2}=\frac{3}{2}$

so, we must compute

$8\times7.50+2\times\frac{3}{2}\times7.50$

since 8 times 7.50 is 60 and 2 times 3/2 is 3, we have

$60+3\times7.50$

Finally, since 3 times 7.50 is 22.5, we get

$60+22.5$

and the answer is $82.5
