Find the percent of increase. round to the nearest tenth, if necessary. from $248 to $255

2.8%

Step-by-step explanation:

Percentage increase is calculated by :

% increase = x 100

The increase = 255 - 248

= 7

Therefore :

% increase = 7 / 248 x 100

% increase = 700/248

% increase = 2.822580645

To the nearest tenth , we have

% increase = 2.8

Good evening ,

Step-by-step explanation:

 Let x be the percent of increase:

  248×[1+(x/100)] = 255

⇔ [1+(x/100)] = 255/248

⇔ [1+(x/100)] = 1.028225806452

⇔ (x/100) = 1.028225806452 − 1 = 0.028225806452

⇔ x/100 = 0.028225806452

⇔ x = 0.028225806452×100 = 2.8225806452

Then  x ≈ 2.8.
