Question

The existing food truck earns $\$3,000$ every day. Steve spends twelve-fifteenths of this amount to buy groceries for the food truck. In $5$ days, how much money is Steve not spending on buying groceries for the food truck?

• A. $\$3,000$
• B. $\$1,000$
• C. $\$90,000$
• D. $\$10,000$

Answer 1

The correct option is A $\$3,000$

Total amount of money earned in a day $=\$3,000$
Total amount of money earned in $5$ days $=\$3,000\times 5=\$15,000$

Fraction of money spent on buying groceries for the food truck $=\frac{12}{15}$
Equivalent fraction of the money spent on buying groceries $=\frac{4}{5}$
Amount of money that is not spent on buying groceries = Whole - Part
Fraction of money not spent on buying groceries for the food truck $=1-\frac{4}{5}=\frac{5}{5}-\frac{4}{5}=\frac{1}{5}$

Amount of money not spent on maintaining the food truck for a month $=\$15000\times \frac{1}{5}=\frac{15000}{5}=\$3000$
