Answer:

He would make $126.70 in 10 hours.

Step-by-step explanation:

First, you have to find the unit rate, in other words, how much money he earns in one hour. To do that, you have to divide.

38.00÷3= 12.666667

Once you know how much money Brandon earns in one hour($12.67), you multiply that number by 10.

12.67×10= 126.70

In conclusion, the answer to this solution($126.70) is how much money he earns in 10 hours.

Answer:

would make $126.67  in 10  hours

Step-by-step explanation:

To find how much Brandon will make in 10 hours, we will follow the steps below:

using proportion,

Let x be the amount he would make in 10 hours

$38  =  3 hours

 x    =   10 hours

cross-multiply

3×x =$38×10

3x = 380

Divide both-side of the equation by 3

\frac{3X}{3}  =  \frac{380}{3}

At the left-hand side of the equation 3 will cancel-out 3 leaving us with just x while at the right-hand side of the equation 380 will be divided by 3, hence;

x ≈$ 126.67

He would make $126.67  in 10  hours
