Question

Gina want to estimate the total of three bills she has to pay. the bills are for $125,$115,and $138. Gina wants to make sure that she has enough money. she wants the estimate to be greater than the total of the bills. should she round to the nearest ten or hundred

Answer 1

The bills are:

125

115

138

Since she wants an estimate that is greater than the actual total, she can round these numbers to the nearest ten.

125 will be rounded to the next tens, which is 130

115 will also be rounded to the next tens, which is 120

138 gets bumped to the next tens, that is 140

The total estimate is the sum of the 3 estimates we just made. That is:

130 + 120 + 140 = $390
