Answer:

Alberta's total overtime pay of the week was $ 145.80.

Step-by-step explanation:

Given that Alberta worked 6 hours at time-and-a-half pay, and 3 hours at double-time pay, and that the value of her regular work hour is $ 9.72, to determine the value of the pay of his overtime, the following equation must be performed:

6x1.5x9.72 + 3x2x9.72 = X

9x9.72 + 6x9.72 = X

87.48 + 58.32 = X

145.8 = X

Therefore, Alberta's total overtime pay of the week was $ 145.80.

guapka [62]

So, there is an exponential growth formula you use.

First, write the initial cost which is

60,000

Then write 1+ the percentage of growth rate which is 0.04 percent. Then, right the time as an exponent after certain amount of years.

60,000(1+0.04)^10

60,000(1.04)^10

Plug this in a calculator

it should be 88814.6571

I hope this helps.
