Question

Jenna bought a gallon of milk at the store for $3.58. About how much change did she receive from a $20 bill?​

Answer 1

If you calculate 20-3.58 the answer is $16.42

Answer 2

Hi! I'm happy to help!

When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:

20.00

- 3.58

We have to borrow:

19.9(10)

- 3.58

10-8=2

19.9(10)

- 3.58

    .  2

9-5=4

19.9(10)

- 3.58

    .42

9-3=6

19.9(10)

- 3.58

    6.42

and 1-0=1

19.9(10)

- 3.58

$16.42

So, Jenna would receive $16.42 in change for her $20 bill.

I hope this was helpful, keep learning!
