Answer:

6.25 hours

Step-by-step explanation:

Proportions:

90 pages  ⇔  2.5 hours

225 pages  ⇔  E hours

E = 225*2.5/90

E = 6.25 hours

6.25 hours = 6 and 1 quarter hours

Maria brought $50 to spend on rides at the
Stels [109]
She has paid for 11 rides.

She started with 50 dollars and at the end she has 6 dollars left. Each ride costs 4 dollars. The follow equation could be created:

$6 = $50 - $4r

Six dollars remaining = original fifty dollars - four dollars per ride.

The number of rides is represented by the variable r.

To solve:

$6 = $50 - $4r
Subtract 50 from both sides

-$44 = -$4r.
Divide each side by -4 to get the number of rides (r)

11 = r

Therefore, she has paid for 11 rides.
