Question

Iris charges a fee for her consulting services plus an hourly rate that is 1 1/5 times her fee. On an 7 hour job iris changed $470. What is her hourly rate

Answer 1

Mark the fee as x. Then, make the following equation :
$x + 7 \times 1.2x = 470 \\ x + 8.4 x = 470 \\ 9.4x = 470 \\ x = 470 \div 9.4 \\ x = 50$
The initial fee is $ 50, and the hourly rate is 1.2 times higher. Thus, the hourly rate is
$50 \times 1.2 = 60$
Her hourly rate is $60.
