You can put this solution on YOUR website!
Let R be the rate of one baker.
11%2AR%2A2.5=89
R=89%2F%2811%2A2.5%29
So then,
P=5.75%2AR%2A1.5
P=%28%285.75%2A1.5%29%29%2F%2811%2A2.5%29%2A89
P=%28%2823%2F4%2A3%2F2%29%2F%2811%2A%285%2F2%29%29%29%2A89
P=6141%2F220
or in decimal,
P=27.91
We can round up to
P=28
