A sporting complex charges $6 to use its facility. The expression 0.25b + 6 models the total cost to hit b baseballs in the batting cages. What is the cost per baseball?

Solution:

Given that,

A sporting complex charges $6 to use its facility

The expression that models the total cost to hit b baseballs in the batting charges is:

Total cost = 0.25b + 6

From given,

6 represents the charge to use the facility

"b" is the number of baseballs

0.25 represents the cost per baseball

Thus, cost per baseball is $ 0.25

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
