Question

Lacey worked 40 hr. at $18.75 per hour. Find her pay using P = RH.

Answer 1

Answer:

750

Step-by-step explanation:

I multiplied the hours she worked by the amount of payment per hour.

Answer 2

Answer:

$750

Step-by-step explanation:

Since Lacey worked 40 hours with the condition that each hours, Lacey will be paid for $18.75, because they worked 40 hours, therefore:

$\displaystyle \large{P = 18.75+18.75+18.75+...+18.75}$

From above, you add from first hour pay to 40th hour pay. However, that’d take quite a long time to evaluate:

$\displaystyle \large{\sum_{H=1}^{40} 18.75 = 18.75 \cdot 40}$

Then evaluate 18.75 * 40 and therefore the solution is $750

For usage of formula:

P = RH for P = pay, H = hour and R = rate (pay per hour)

So if you use the formula, you’d still end up with P = 18.75*40 which is $750
