Question

Hey can anyone help me check if this is right pls?: 7th grade Algebra Percent Models: "John's dad is willing to pay for 30% of the cost of his first vehicle. If John plans to buy a car for $7,499, how much does John contribute to the cost of the vehicle? Round to the nearest cent."

Answer 1

well, his dad is paying 30% of the vehicle, so John will end up paying the rest, 100% - 30% = 70%.

`\begin{array}c \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{70\% of 7499}}{\left( \cfrac{70}{100} \right)7499}\implies 5249.30`
