3.)
Variables:
New tablet cost (575),
Money already saved, (56),
Money saved per week(14w)
Write an Equation:
The amount of weekly money you need to earn must cover the leftover cost needed to buy the tablet, therefore:
money_needed - money_you_have = money_earned_per_week
575 - 56 = 14w
Solving:
575 - 56 = 14w
519 = 14w
37.071428 = w
37 weeks needed
You solve the other two on your own.
