Tia Walls · Answer 1

If he needs $565 and he owes his sister $65 then you add $565 and $65 to get a total of $630 which you then divide by $30 because that's how much he saves a week and you get a total of 21 weeks.

Your equation would be:

565 + 65 = 30x

Christopher Anderson · Answer 2

Okay, So We Need To First Write An Equation So We Can Solve It.

C = Cost

D = Deposit

T = Time

S = Sister Debt

T = (C + S) / 30

So, Plug In The Known Values.

T = (565 + 65) / 30

565 + 65 = 630.

T = 630/30

630/30 = 21

T = 21

So, It Will Take Steven 21 Weeks Of Depositing $30 To Buy His Bike.
