Answer:

y = -5x + 6

Step-by-step explanation:

y = 1/5 x + 4/5

so that two lines are perpendicular, its slope must be opposite and reciprocal

y = m x + b

m: slope           perpendicular  -1/m

if our formula is     y = 1/5 x + 4/5

m = 1/5

so the slope of our new formula will be

m' = -5/1

m' = -5

now if you tell us that you have to go through a certain point  (1/1)

we just have to replace the values ​​in the following formula and solve

y - y1 = m ( x - x1)

y - 1 = -5 ( x - 1)

y = -5x + 5 + 1

y = -5x + 6

Winston ears 140$ by selling 56 hotdogs at the concession stand at school. Using the same rate for the cost of one hot dog how m
WARRIOR [948]

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
