Can someone help me real quick it costs $4 to enter the fair. each ride costs $2.50. you have $21.50. how many rides can you go on?

(P. S. can you right the equation/ inequality, please)

Hello!

We can write an expression to show this scenario. Write this in the equation format y = mx + b:

m = rate of change, or cost per ride

b = initial cost, or cost to enter the fair

y = 2.50x + 4

Solve for the amount of rides possible with $21.50:

21.50 = 2.50x + 4

Subtract 4 from both sides to isolate x:

17.50 = 2.50x

Divide both sides by 2.50:

17.50/2.50 = 7 rides.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
