What is 380 increased by 5%?
Anna35 [415]
The answer would be 399.

First you'd find 5% of 380.
To get a decimal point for 5% you just need to move the percent sign twice to the left.
5% ➡ .05

Now multiply .05 with 380
380 × .05 = 19

Since you're finding the increase of 5% along with 380 you add it together
380 + 19 = 399
