A grocery store bought ice cream for $2.50 per half gallon and stored it in two freezers. During the night, one freezer malfunctioned and ruined 13 half gallons. If the remaining ice cream is sold for $3.90 per half gallon, how many half gallons did the store buy if they made a profit of $89.30?

step-by-step explanation:

for the free

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
