Question

At the candy store, a chocolate bar costs c dollars and a vanilla bar costs 2 dollars more than a chocolate bar. Jamie buys a chocolate bar and three vanilla bars, and Kevin buys five chocolate bars. How much money, in total, do Jamie and Kevin spend at the candy store in terms of c?

Accepted Answer

Since each chocolate bar costs c dollars, each vanilla bar costs c+2 dollars. Jamie spends c+3(c+2) dollars, and Kevin spends 5c dollars. Their total, in dollars, is thus c+3(c+2)+5c=c+3c+6+5c=9c+6.
