The number of hotdogs that must be sold to earn $170 is 70
What is the formula for total earnings?
The total earnings can be determined as the price per hotdog multiplied by the number of hotdogs sold, which is as shown below:
total earnings=price per hotdog*number of hotdogs
total earnings(initially)=$140
price per hotdog=P
number of hotdogs=56
$140=P*56
P=4140/56
P=$2.50
Now, we need to determine the number of hotdogs required to earn $175
$175=$2.50*X
X=$175/$2.50
X=$70
