Let's calculate the total cost of Baker's purchases:
1. Golf balls: $12.50
2. Tees: $1.79
3. Golf shirt: $27.99
4. Sales tax: $2.96
Total cost = $12.50 + $1.79 + $27.99 + $2.96
Now, let's find Baker's change from $50.00:
Change = $50.00 - Total cost
Perform the calculations to determine Baker's change.
1. Golf balls: $12.50

Total cost = $12.50 + $1.79 + $27.99 + $2.96
Now, let's find Baker's change from $50.00:
Change = $50.00 - Total cost
Perform the calculations to determine Baker's change.
Answer: $4.76
Explanation
Add up the three costs and the sales tax at the end.
12.50+1.79+27.99+2.96 = 45.24
Subtract this amount from 50
50 - 45.24 = 4.76
----------------------
Need a way to find the change without a calculator? To go from 24 cents to 30 cents is "add 6 cents" because 24+6 = 30. Then from 30 to 100 is "plus 70". So far we increased by 76 cents when going from 24 to 100.
Adding 76 cents means $45.24 becomes $46.00; then from $46 to $50 is "increase by $4".
Put together "increase by $4" and "increase by 76 cents" to end up with $4.76
Effectively we think of subtraction as a form of backwards addition in a way. With enough practice, you can do these kind of calculations in your head fairly quickly.
