Question

If there were 300 accidents in 1967 and 380 in 1968, what is the percent increase?

Answer 1

Answer:

As per the statement:

If there were 300 accidents in 1967 and 380 in 1968.

Number of accident in 1967= 300

Number of accident in 1968= 380

then;

Increase in accident = 380-300 = 80

Using formula to find the percent increase:

$\text{Increase in percent} = \frac{\text{Increase in accident}}{\text{Number of accident in 1967}} \times 100$

Substitute the given values we have;

$\text{Increase in percent} = \frac{80}{300} \times 100$

Simplify:

$\text{Increase in percent} = \frac{80}{3} = 26\frac{2}{3} \%$

Therefore, $26\frac{2}{3} \%$  is the percent increase

Answer 2

First find the amount of increase: 380-300=80. Then divide the amount of increase by the original amount: 80/300=.266666667. Normally you round to the tenths place: .27. Then make it a percent: .27=27%. The percent of increase is 27% :) hope this helps
