Question

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

Answer 1

750

Explanation:

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

Answer 2

$750

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
