To find out how much money Andrew and Becky have to spend on a video game, you need to calculate the sum of their allowances. Since Andrew and Becky both earn $3 an hour for doing chores, you'll need to know how many hours they each spent doing chores.

Let's assume that Andrew worked for 5 hours and Becky worked for 4 hours. Now, multiply the number of hours each of them worked by their hourly rate:

Andrew's earnings: $3 × 5 hours = $15
Becky's earnings: $3 × 4 hours = $12

To find the total amount of money they have together, you simply add Andrew and Becky's earnings:

$15 + $12 = $27

Therefore, Andrew and Becky have a total of $27 to spend on a video game.
