Ahealth insurance payment of $34.55 was deducted from ms. donaldson's earnings for the week. after the insurance deduction, payroll taxes equal to 28% of the balance were deducted. what was the amount that ms. donaldson received?

I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10

So the 34.55 were deduced from this number, and the remaining amount was:

907.10-34.55=872.65

After this, further 28% were deduced, which means that 100-28=72% were left.

And this is:72%*872.55= 628.236 (which we round to 628.24!)
