Ayear ago, leila wanted to buy a necklace that cost $25.00. this year the same necklace cost $30.00. what was the percent increase of the price of the necklace?

20 %

Step-by-step explanation:

% Increase = Increase/Original value × 100 %

Data:

 Original = $25

This year = $30

Calculations:

   Increase =  This year - original

                  =         30       -      25

                  =                   $5

% Increase = 5/25 × 100 %

                  = 20 %

The percent increase of the price of the necklace was 20 %.
