A rental car company rents a compact car for $20 a day, plus $0.25 per mile. A midsize car rents for $30 a day, plus $0.20 per mile.
a. Write a linear function representing the cost to rent the compact car for x miles.
b. Write a linear function representing the cost to rent the midsize car for x miles,
c. Find the number of miles at which the cost to rent either car would be the same.

a

step-by-step explanation:

strong negative correlation

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
