Ronny is selling coffee mugs for $5.00. So far, he has earned $450.00. Ronny needs to earn more than $630.00 in order to meet his sales goal. How many more coffee mugs, x, does Ronny need to sell in order to reach his sales goal?

9514 1404 393

  36

Step-by-step explanation:

The equation for Ronny's total sales can be written as ...

  450 +5x = 630 . . . . . where x is the number of additional mugs to be sold

  5x = 180 . . . . . . . subtract 450

  x = 36 . . . . . divide by 5

Ronny needs to sell 36 more coffee mugs to reach his sales goal.

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?
