Question

At the office supply store, a ream of paper costs $5.89 and a cartridge of ink costs $39.40. Frances needs to buy 7 reams of paper and 9 cartridges of ink for her office. She needs to know how much money to bring, so estimate the cost of these supplies

Answer 1

Solution: $ 395.83

Analysis: We know the value per unit of a ream of paper and a cartridge of ink.

Cost of 1 ream of paper: $5.89

Cost of 1 cartridge of ink: $39.40

Now, we need to find the value of 7 reams of paper and 9 cartridges of ink. In that case, we can multiply each amount by the value.

Answer 2

Solution: $ 395.83

Analysis: We know the value per unit of a ream of paper and a cartridge of ink.

Cost of 1 ream of paper: $5.89

Cost of 1 cartridge of ink: $39.40

Now, we need to find the value of 7 reams of paper and 9 cartridges of ink. In that case, we can multiply each amount by the value.

`\begin{gathered} Total\text{ }cost=(7\ast5.89)+(9\ast39.40)=41.23+354.6 \\ Total\text{ }cost=395.83 \end{gathered}`
