Question

Please help me with my homework im stuck on this

Answer 1

a) In the tape diagram, each one of the (x-2)-sections represents one week that Andre worked. The 40 above the 5 sections indicates that after 5 weeks, he will save $40.

b) Algebraically, the tape diagram is

`5(x-2)=40`

Solve for x as shown below

`\begin{gathered} \Rightarrow5x-10=40 \\ \Rightarrow5x=50 \\ \Rightarrow x=(50)/(5)=10 \\ \Rightarrow x=10 \end{gathered}`

The answer to part b. is $10.
