Mary is looking to hire someone to snow plow her driveway for the winter. John charges $50 for the season plus an additional $20 per plow. Jim charges $75 for the season, plus an additional $15 per plow. How many plows until the two charge the same amount of money?

According to CostHelper, the cost for one worker to shovel or snow blower can cost between $25 to $75 an hour. The cost to hire a company to plow a standard driveway after a storm can run about $30 to $45 per storm.

"if it is my birthday, then it is snowing"

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
