Ans 2.(a)

Amount of the tip = 20% of the food cost.

Food Cost = Total Cost - Tax

=> Amount of Tip = 20% of Total Cost - Tax

(b)

Amount of tip = 0.20(25.62 - 1.22) = 4.88

Round off = $5

Ans 4.

Total money borrowed = $6900

Money returned = $250 per month

Time required = Total money borrowed/Money returned per month

Time = 6900/250 = 27.6

It will take 28 months to return the money
