If your parents give you $2 a week for allowance, then your “Income” (or Money) is $2. If you want to buy a toy that costs $6, then you know you won’t have enough money yet. You only have $2 now. So you have to earn 4 more dollars to buy the toy. $6 Toy - $2 “Income” (Money) = $4 Still Needed to Buy the Toy. If you save your allowance for three weeks, then you can buy the toy! $2 Week 1 Allowance + $2 Week 2 Allowance + $2 Week 3 Allowance = $6 Total “Income” (Money) If you save your money for three weeks, you will have enough money to buy the toy!
