let d(t) be the total number of miles joanna has cycled and let r represent the number of hours after stopping for a break during her ride

PLEASE MARK BRAINIEST

d (4) = 68

This means that after 4 hours Joanna cycled for 68 miles total

Step-by-step explanation:

For this case we have the following equation:

The variables are:

t: time in hours

d (t): distance traveled in miles.

We evaluate the distance traveled after 4 hours.

So we have that for t = 4:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

i think the answer is fried chicken ; >
