Kareem has three gift cards in his wallet for the same store. Gift cards A, B, and C had original balances of $50, $75, and $80, respectively. Gift card A has a remaining balance that is $4.91 more than half of the original balance. Gift card B has a remaining balance that is 19% of the original balance. Gift card C has a remaining balance that is of the original balance. Use estimation strategies to complete the statements below. Kareem estimated he could buy a watch that costs $80 using only his three gift cards. Kareem's estimate of $80 reasonable because the total remaining balance for all three gift cards is approximately $, which is the cost of the watch he wants to buy. Kareem buy the watch using only his three gift cards.
