Christian and Sue wanted to get a $50.00 bottle of perfume for their mom for her birthday. Christian had $5.00 saved up and Sue had $7.00. Christian then mowed 4 of his neighbors' yards, charging $5.00 each, while Sue walked 6 dogs for her neighbors, charging $2.00 per dog. How much more money will Christian and Sue need to make in order to buy the bottle of perfume for their mom?
Let's think step by step.
6
Christian just mowed 4 yards at $5.

00 each so he made 4 * 5 = $20.

00.

Sue just walked 6 dogs at $2.

00 each so she made 6 * 2 = $12.

00.

Christian had $5.

00 saved and just made $20.

00 while Sue had $7.

00 saved and just made $12.

00 so together they had 5 + 20 + 7 + 12 = $44.

The perfume cost $50.

00 and they had $44.

00 so they needed to make 50 - 44 = $6.

00 more dollars.

.

Thus, the answer is 6
