Miss Hernandez has $100 to spend on parking and admission to the zoo the parking will cost $7 and Mission tickets will cost 1550

Mandarinka [93]

It should say $15.50. Parking = p. n = number of people.

n15.50 + 7 is the equation.

She can bring 6 people, because (6 * 15.50) + 7 = $100
Glad to help!

Let fx) = 8x - 3<br> What is f(5)?

mihalych1998 [28]

f(5) means to replace the x in the equation with 5.

f(5) = 8(5) - 3

f(5) = 40 - 3

f(5) = 37
