Answer 1

In order to determine the percent increase, proceed as follow:

Subtract 165 to 178:

178 - 165 = 13

Now, consider that 13 is the x percent of 165, then, you can write:

$\frac{x}{100}\cdot165=13$

by solving for x and by simplifying, you have:

$x=13\cdot\frac{100}{165}\approx7.8$

Hence, the percent increase is approximately 7.8%
