julia-pushkina [17]

Answer: $75.83

Step-by-step explanation:

Seth needs $9,100 and his grandparents will pay 70% of this:

= 9,100 * 70%

= $6,370

The amount Seth has to save for is therefore:

= 9,100 - 6,370

= $2,730

He has 3 years to save for it and wants to save monthly. In months this is:

= 3 * 12

= 36 months

Minimum amount to save every month is:

= Amount to save/ Number of months

= 2,730 / 36

= $75.83
