Question

bill has been $6 each week. today he spent $90 of the savings, and he now has $48 left. for how many weeks has he been saving. ( answer both A and B)​

Answer 1

23 weeks

Step-by-step (x = weeks)

`90 + 48 = 138`

divide 138 by 6 to find out how many weeks he'd been saving up .

that gives you 23 but to turn it into an equation

`6x - 90 = 48`

`+ 90 +90`

`6x = 138`

_ _

`6`
`6`

`\bold{x = 23}` again x meaning weeks
