(b) Solve the equation. Show your work.

(c) Check your solution. Show your work.

(d) State the solution in complete sentences.

Answer 1

A.

4x=y

3(2.5+x)=y

4x=3(2.5+x)

B.

4x=7.5+3x

x=$7.5

4x=y

4(7.5)=y

y=$30

C.

3(2.5+x)=y

3(2.5+7.5)=y

y=$30

D.

Brian bought four items costing $7.50 each while Chris bought three items each costing $10. They each spent $30 on party favors and a total of $60 all together.
