Tomas orders a meal that costs $7.89. Lisa's meal costs $9.05. About how much is the combined cost of their meals?

1 Answer

#$8+$9=$17#

Explanation:

This is a question on Estimation - which is a very important skill!

We have two meals:

  • the first meal was $7.89, which is roughly $8
  • the second meal was $9.05, which is roughly $9

So we can say that the two together were roughly #$8+$9=$17#
