The interest rate on an auto loan in May was 12 %. By September the rate was up to 14 %. How many percentage points did the interest rate increase over the period?

How would I begin this?

would this be 1.68%

14%-12% = 2 percentage points.

it is actually 14 1/4% and 12 3/8%

sorry I forgot to insert the fraction

Ye gads! Why didn't you post the correct figures in your first post?

would i subtract 12 3/8% from 14 1/4%?

sorry Ms. Sue I didn't read the problem correctly

Yes, 14 1/4 - 12 3/8 = ??

the answer I got was 2 5/8

is this correct DrBob
