P(A U B) = P(A) +P(B) - P(AB) \\  \\ = \frac{7}{20} +\frac{3}{5} - \frac{21}{100} \\  \\ = \frac{35}{100} +\frac{60}{100} - \frac{21}{100}  \\  \\ =\frac{74}{100}  \\  \\ =\frac{37}{50}

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.
Nitella [24]

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

\mathbf{C(t) = 87t + 32}

A linear function is represented as:

\mathbf{C(t) = mt + b}

Where:

m represents the slope or the unit rate.

So, by comparison:

\mathbf{m = 87}

This means that 87 represents the slope and the cost per tire purchased
