An amusement park reduced the admission price to $15.50 per day, but now charges $1.50 per ride. Mark has $26 to spend on admission and rides. Write an algebraic equation to find how many rides Mark can ride in one day.

A + 1.50r = 26.00

Step-by-step explanation:

A is the admission price, which is $15.50. So A = 15.50. Substitute 15.50 for A and subtract 15.50 from each side

    A + 1.50r = 26.00

    15.50 + 1.50r = 26.00

    1.50r = 10.50

Divide each side by 1.50.

    1.50r = 10.50

    r = 7

Mark can ride 7 rides in one day.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
