The total cost of the lease would be $17,200. This is because $300 payment for 24 months is equal to $7,200 + $1,000 (down payment) and + the residual value of $9,000 = $17,200.
Yes he does have enough lemon juice to make 4 glasses of lemonade.
1. Find how much lemon juice he used
4*5=20
2. Find how much lemon juice was left
28-20=8
3. Compare how much lemon juice was left to what he needed to make 4 glasses of iced tea.
4*2=8
