Question

Increase or decrease each amount by the given percent. Find the answer to the nearest cent.

$1.50; + 5%

Answer 1

Basically you just have to find 5% of $1.50 and add it to $1.50 and there's your answer.
To convert a percent to a decimal, move the decimal 2 places to the left, making 5% = .05
\[1.50 \times .05 = 0.075\]
So, 5% of $1.50 is 0.075. Add that to $1.50:
\[1.50 + 0.075 = 1.575\]
Rounding it to the nearest cent makes your answer:
$1.58
