question

Elena wanted some extra spending money, so she took some old stamps and baseball cards to sell at the flea market. She sold 88 items in total. If Elena sold 15 old stamps, about how many baseball cards did she sell? Choose the better estimate.

100

solution

Subtract the number of old stamps sold from the total number of items sold.

88 − 15 = ?

Round each number to the nearest ten.

88	–	15	= ?

90	–	20	= 70

70 is the better estimate.
