Write the inequality and show all work to solve the inequality.

Answer 1

Ooo gotta get those games!

So we're buying a game for 12, and each add-on for 4.50.
Let's label the number of add-ons that we purchase as A.

So in total the amount of money we're spending at the mall is
12 + 4.50A

This is 12 for the game, and 4.50 times the number of add-ons we purchase.
And we're told this total amount must be `at most` (which is the same as `less than or equal to`) 23 dollars.

\(\rm 12+4.50A\le23\)

Answer 2

Solve for A.
