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 .

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
