3. melissa is buying party favors to make gift bags. supplies ltd sells a 5 - pack of favors for $11.25 and parties and more sells a 3 - pack of favors for $8.25. at these rates, how much will she save if she buys 15 favors from supplies ltd than parties and more? (example 1)
Answer
Explanation:
Step1: Calculate the cost from Supplies LTD
Since Supplies LTD sells a 5 - pack for $11.25, and 15\div5 = 3 packs are needed. The cost is (11.25\times3). [11.25\times3=(11 + 0.25)\times3=11\times3+0.25\times3=33 + 0.75=33.75]
Step2: Calculate the cost from Parties and More
Since Parties and More sells a 3 - pack for $8.25, and 15\div3 = 5 packs are needed. The cost is (8.25\times5). [8.25\times5=(8+0.25)\times5=8\times5 + 0.25\times5=40+1.25 = 41.25]
Step3: Calculate the savings
Subtract the cost from Supplies LTD from the cost from Parties and More. [41.25-33.75 = 7.5]
Answer:
(7.5)
