Question

Jeff purchased 7 gumballs for $0.25 each and 3 pieces of gum. He spent a total of $2.05. How much did each piece of gum cost?

Write the equation for this
problem.

Answer 1

Answer: (0.25 x 7) + 3x = 2.05 and $0.10 per piece of gum

Explanation:

Jeff purchased 7 gumballs for $0.25 each, which is
`(0.25*7)`

Jeff then purchased 3 pieces of gum, but we don't know for how much so the cost becomes
`x` and then
`3x`

The final cost then comes down to $2.05, therefore
`(0.25*7)+3x=2.05` and solve for
`x` to find the cost of each piece of gum

`1.75+3x=2.05`

`3x=0.3`

`x=0.1`

Answer 2

Each piece of gum is 10cents

Explanation:

7 x 0.25 then subtract that from 2.05 then divide by the 3pieces of gum
