Question

A 100$ printer cost 44$ less than eight times the cost of a ream of paper. How much is a ream of paper?

Answer 1

`\begin{gathered} \text{priter price is}\Rightarrow100\text{ \$} \\ \cos t\text{ of ream of paper is }\Rightarrow x \\ \text{Now,} \\ 8x-44=100 \\ 8x=144 \\ x=18\text{ \$} \end{gathered}`
`\begin{gathered} \text{samara's age is }\Rightarrow x \\ \text{rayah's age is}\Rightarrow x-4 \\ \text{now, } \\ 2(x-4)=12+x \\ 2x-8=12+x \\ x=20 \\ \text{samarah 's age is}\Rightarrow20\text{ years} \\ \text{rayah's age is}\Rightarrow20-4=16\text{ years.} \end{gathered}`
