You are paid $82.50 for 7 1/2 hours of work, whats is your rate of pay?

ra1l [238]

Answer:

Rate of Pay is $11 per hour.

Step-by-step explanation:

Cost of $7\frac{1}{2}\:hr$ of work = $ 82.50

To find: Rate of pay

Here Rate of Pay means Cost of 1 hour of work or we can say cost of per hour work.

$7\frac{1}{2}=\frac{7\times2+1}{2}=\frac{15}{2}$

⇒ Cost of $\frac{15}{2}\;hr$ of work = $ 82.50

Cost of 1 hr of work = $\frac{82.50}{\frac{15}{2}}$

= $\frac{82.50\times2}{15}$

= $\frac{165}{15}$

= $ 11

Therefore, Rate of Pay is $11 per hour.
