Ben and jerry’s sells 2 times more ice cream cones ($2) than shakes ($9). if last month’s sales totaled $3,900, how many of each were sold?

Given

Ben and jerry’s sells 2 times more ice cream cones ($2) than shakes ($9)

last month’s sales totaled $3,900

Find out how many of each were sold.

To proof

Let us assume the number of shakes sold be x

as given in the question

they sell 2 times more ice cream cones  than shakes

than  the number of ice cream sold = 2x

sales totaled = $3,900

shakes cost = $9

ice cream cost = $2

FORMULA

value of the ice cream cones + value of the shakes = total cost

2x (2) + x(9) =  3900

4x + 9x = 3900

13x = 3900

x = 300

The number of shakes sold be 300

The number of ice cream cone sold be 600

Hence proved
