A grocery store reduced the price of a loaf of bread from $3.30 to $3.25. Find the percent change (discount rate). Round to the nearest tenth of a percent.

3.25/3.30 = 0.985 = 98.5%.

%Change = 98.5% - 100% = -1.5% = 1.5% Decrease.

To find the percent change (discount rate) for the price reduction of the loaf of bread, you need to calculate the difference between the original price and the new price, and then express that difference as a percentage of the original price.

First, subtract the new price from the original price:
$3.30 - $3.25 = $0.05

Next, divide this difference by the original price:
$0.05 / $3.30 = 0.0152

To express this as a percentage, multiply the result by 100:
0.0152 * 100 = 1.52

Therefore, the percent change or discount rate is approximately 1.52%.
