Given:
Total money she had = $9
Cost of each pack of candles = $1.50
Cost of each tube of colored frosting = $2.75
Let's find the number of colored frosting she can buy.
Since she has to buy 2 packs of candles, the total cost she would spend on candles is:
Cost of candles = $1.50 x 2 = $3.00
Thus, we have the inequality:
2.75x + 3.00 ≤ 9
Where x represents the number of tubes of colored frosting she can buy.
Let's solve for x.
2.75x + 3 ≤ 9
Subtract 3 from bith sides:
2.75x + 3 - 3 ≤ 9 - 3
2.75x ≤ 6
Divide both sides by 2.75:
Since x is less than or equal to 2.18, this means Jane can buy no more than 2 tubes of colored frosting.
ANSWER:
No more than 2 tubes
