Whats the upper bound for estimate for 354 + 267?

Mathematics
1 answer:
quester [9]2 years ago

Personally I'd replace 354 with 360 and 267 with 270, and then add 360 and 270, obtaining 630.  Similarly, estimate 63.75 + 3.63 by adding 60 and 3:  63.  There's no single answer for either problem.  For "upper bound," I round the given addends upward; for "lower bound," I found the addends down.

In 2021, the Internal Revenue Service (IRS) decreased the deductible mileage cost to 56 cents from 57.5 cents. Find the percent
Anon25 [30]

The deductible mileage cost has reduced by 2.16%

What is a percentage change?

A percentage change  compares the difference between the new amount and the old amount to the old amount.

I mean the percentage change is the new deductible mileage cost minus the old deductible mileage cost divided by the old deductible mileage cost

New deductible mileage cost= 57.5 cents

Old deductible mileage cost= 56 cents

percentage decrease=(56-57.5)/57.5

percentage decrease=-2.61%

The negative sign in -2.61% means that there was a percentage decrease in deductible mileage cost by 2.61%

In essence, the deductible mileage cost has been reduced by 2.16%

Hundredth of a percent means two decimal places.
