Janiyah got her car fixed at Sincere’s Auto. Sincere, being a man of few words, gave her the following information when she asked for an estimate: “3 hours, $375. 5 hours, $495.” What is the rate of change?

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

(x) - (y) = (1 + 4i)
