Jackie pays for her groceries with a $50 bill. she receives $2.89 in change. how much did her groceries cost?

$47.11

Explanation:

The change is what is left over. If she paid with $50 and got back $2.89, the difference is the price of the groceries she bought.

50 - 2.89 = 47.11

0.18 days

Step-by-step explanation:

There are 24 hours in a day, so to find out how many days are in x hours we need to divide x by 24.

x/24 = # of days

x - 4.3

4.3/24 = 0.179

We can then round this up to 0.18

Therefore, there are 0.18 days in 4.3 hours
