Remember, you can do anything to an equation as long as you do it to both sides

we hates fractions
multiply both sides by 4
3d-2=28
add 2 to both sides
3d=30
divide both sides by 3
d=10

tiny-mole [99]

Answer:

y = 10 + 2.50h

$25

Step-by-step explanation:

first the equation is written as such because she pays $10 no matter how many hours she rides. She also pays 2.50 for each hour so use h as the variable to define number of hours she rides the bike.

since equation is y = 10 +2.50h

and h = 6 hours, substitute and find the total cost

y = 10 + 2.50(6)

= 10 + 15

= $25
