Question

30. A mom bought her kids 3 cartons of milk

for $1.25 each and 6 doughnuts. The total
cost was $6.90. Write an equation to
determine the cost of a doughnut.

Answer 1

$3.15

Explanation:

$1.25x3=$3.75

$6.90-$3.75=$3.15

Answer 2

x = (1.25 * 3 - 6.90) divided by 6

Explanation:

this will get the price of all the milk, then take it out of the total price, then divide it by 6 because there are 6 donuts, this will give you the price of 1 donut
