Question

Abby Boernet has yet to receive 60% of her lobster order. Abby received 80 lobsters to date. What was her original order?

Answer 1

so Abby hasn't received 60% of her order, BUT she already got 80 lobsters, hmmmmm well, 100% - 60% is just 40%, so she already got the 40%, which incidentally is 80 lobsters. Let's say the whole order, or 100% of it is "x" lobsters.

if 80 lobsters are 40%, what is "x"?


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ x&100\\ 80&40 \end{array}\implies \cfrac{x}{80}=\cfrac{100}{40}\implies x=\cfrac{80\cdot 100}{40}`
