First you need to figure out the total cost pre-tax:

$24.98 x 3 = $74.94

Now to figure the tax. The rate is 4% of the total cost. That is another way of saying 4/100ths, or .04

$74.94 x .04 = $2.9976

This needs to be rounded up.

So, the answer to the problem -- which asks for the amount of sales tax, is $3.00.

The total cost, if you need that too, is:

$74.94 + $3.00 = $77.94

multiply 24.98 by 3 

24.98 x 3 = 74.94

 divide 4 by 100 which would be .04

multiply:

74.94 x .04 = $2.9976

round up: 

$2.9976 = $3

add it to 74.94

74.94 + 3 = 77.94

the price is $77.94

74.94 x .04 = $2.9976

round up: $2.9976 = $3

add it to 74.94

74.94 + 3 = 77.94
