Answer 1

(a) At Garcia's Bike rentals, it cost $33 to rent a bike for 8 hours.

We are asked to find how many dollars will an hour of bike use cost.

Let x be the cost in dollars of an hour of bike us.

If 8hours = $33

1 hour = $x

Lets cross multiply:

8 * x = 33 * 1

8x = 33

Let's divide both sides by 8

x = 33/8

x = $4.125

Therefore, per hour of bike use is $4.125

(b) Keiko bought 12 pounds of flour for $6.

We are to find how many dollers she paid per pound of flour.

Let y be the amount in dollar he paid per pound of flour.

If 12 pound = $6

1 pound = $y

Let's cross multiply:

12 * y = 6 * 1

12y = 6

Divide both sides by 12:

y = 6/12

y = $0.5

Therefore, she pays $0.5 per pound of flour.
