The gift bag from Claire Cosmetics includes 5 bottles of nail polish and 2 tubes of lip gloss. Use p to represent the cost of each bottle of nail polish and g to represent the cost of each tube of lip gloss. Write and simplify an expression that represents the total cost of 8 gift bags.
p = polish g = gloss bc = gift bag cost As the cost is not given, assuming that the costs will be given for each item separately, we can state that the cost of p is X, and the cost of g is Y: [(5p x X) + (2g x Y)] x 8 = bc
