On Saturday and Sunday jarrod went running and burned a total of 6475 calories he burned 320 of those calories on Saturday which addition equation could be used to find the number of calories c jarrod burned on Sunday A 647.5+c=320
B. 320 + c = 647.5
C. 320 + 647.5=c
D. 647.5 + 320 =c

The answer is B.

Step-by-step explanation:

It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.

$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)
