In order to find the number of hours of work at which they will have the same amount, you will need to find both their equations and then equalize them to find when they are the same. Let x be the number of hours Fernando: intial 10$ = constant and we multiply x by the 4$ he takes per hour. The whole has to be multiplied by 0.30 (30%) since that is the only part he keeps Therefore, yf=0.3(4x+10) Brenna: same logic yb=0.25(6x) To find when they are equal: yf=yb 0.3(4x+10) = 0.25(6x)

Answer:

x = 21

Step-by-step explanation:

You can solve this problem by using similar triangles. You can tell that the two triangles are similar by AAA (since two angles are the same, the third must be too).

Now that we've established that the triangles are similar, you need to identify the corresponding sides:

12 corresponds to 28

9 corresponds to x

In order to find x, you'll need to find the scale factor, which you can find by dividing 28 by 12:

28 ÷ 12 = 7/3

Now that you know that 7/3 is the scale factor, you can multiply it by 9 to find x:

9 × 7/3 = x

x = 63/3

x = 21
