Answer:
A, $151.36
Step-by-step explanation:
Step #1: Change 5.3% to a decimal.
To do that just move the decimal point 2 places to the left (same thing as dividing by 100). Also remember that every number has invisible zeros in front of it that don't change the number at all.
So basically to change 5.3% to a decimal just move the decimal point in front of 5 (that's one time), then in front of the invisible zero (that's 2 times) so you have .053
Step #2: Then multiply .053 times $143.74
The answer should be $7.61822 if you did it right.
Step #3: Add #143.74 and $7.61822 to find the total with the sales tax.
The answer should be $151.35822.
But we don't do that in money so round the total to the nearest cent. Look at the third decimal space to see if you're rounding up or down. If the decimal space is 0-4, then round down (so in this case if the 8 was a 2, you would keep the 5 like it is and the answer would be $151.35). But if the third decimal space is 5-9, then round up.
In this case since the third decimal space is a 8, we are rounding up and changing the 5 to a 6.
So your final answer should be $151.36.
