Write the inequality to find the greatest number of bottles she can buy.

Answer to Problem 70S
Inequality equation:
She can buy 2 bottles of soda.
Explanation of Solution
Given:
Rita is ordering a pizza for $14.49 and a few 2 − liter bottles of soda. She has $25 to spend. The cost of delivery and tip is $5. If each 2 − liter bottle costs $1.99.
Concept Used:
Money with Rita = $25
Cost of pizza plus cost of delivery and tip:
Amount left over for soda:
Number of bottles of soda she can buy be x
Inequality equation:
Calculation:
Inequality equation:
Solve for x, the number of soda bottle.
Since she can only buy a whole bottle of soda, she can buy 2 bottles of soda.
Thus, she can buy 2 bottles of soda.
