Find the new amount 2000 miles increased by 33%
Goryan [66]

Answer:

2,660\ miles

Step-by-step explanation:

we know that

The amount of 2,000 miles represent 100%

If the amount is increased by 33%

then

The new percent of the amount will be

100%+33%=133%

so

using proportion

\frac{2,000}{100\%}=\frac{x}{133\%}\\\\x=2,000(133)/100\\\\x=2,660\ miles
