The average cost for a gallon of gasoline increased from $2.56 one year to $3.18 the next year. what is the percent of increase, rounded to the nearest whole number? a.) 19% b.) 24% c.) 26% d.) 29%

B.) 24%

Step-by-step explanation:

Given : The average cost for a gallon of gasoline increased from $2.56 one year to $3.18 the next year.

Increase in cost ( in dollars) = 3.18-2.56=0.62

The formula to find the percent decrease :-

Hence, the percent of increase = 24%

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?

answer is b
