Question

Estimate to the nearest whole number: 2(88.5) + 3(39.7) −14.2

PLEASE HELP ME

Answer 1

2(88.5) = 177 3(39.7) = 119.1
177 + 199.1 = 296.1
296.1 - 14.2 = 281.9
281.9 rounded to the nearest whole would be 282

Answer 2

284

88.5 estimated is 89

39.7 becomes 40

-14

Multiply 89 by two: 178

Multiply 40 by 3: 120

Subtract 14

And we have 284.
