Kari bought 3 gallons of milk that cost 3.79 if she paid the cashier with a 20 bill how much change should kari receive

Cost of 3 gallons of milk =3.79

Amount Kari paid =20

difference =20-3.79 = 16.21

so she will receive 16.21 back

Here the price of 1 gallon of milk is $3.79. SO price of 3 gallons of milk = 3.79 * 3= $11.37. But she gives the cashier $20 .

So to find the change Kari shoul receive, we need to subtract the price of 3 gallons of milk from $20 = 20 -11.37 = $8.63 .

THerefore Kari receive $8.63 as change from cashier .
