Answer:
Step-by-step explanation:
2 lb bag to 4 sq ft = 1 lb bag to x sq ft
2 / 4 = 1 / x
cross multiply because this is a proportion
(2)(x) = (1)(4)
2x = 4
x = 4/2
x = 2 <==== so a 1 lb bag covers 2 sq ft
First we need to calculate the total cost.
The seniors will rent limousine from 8:00 pm till 1:00 am. So total time of rent = 5 hours
Total charges = Charges of first 3 hours + Charges of next 2 hours + Tip
So,
Total charges = $180 + 2($30) +$20 = $260
Thus the total amount the 8 seniors will have to pay is $260. The amount each senior will have to pay is $260/8 = $32.5
Therefore, each student will have to pay $32.5
