2. GASOLINE In mid-2005 the average price of 5 gallons of regular unleaded gasoline in the United States was $12.95. What was the price for 16 gallons of gas?

$41.44

Step-by-step explanation:

12.95÷5=2.59

2.59 is the unit rate, so price for gallon.

2.59×16(gallons)= 41.44$

16 + 8b ≥ 50

4500

Step-by-step explanation:

He needs at least 50 rooms and has already reserved 16

They are in groups of 8

16 + 8b ≥ 50

Subtract 16 from each side

16+8b-16 ≥ 50 -16

8b≥ 34

Divide by 6

8b/8 ≥ 34/8

b≥ 4.25

We need to round up since we need at least 50

b = 5 since we want the least amount of rooms

Each block is 900

5*900 = 4500 more that he will have to spend
