Given:
A haircut cost $20.Sales tax is 4.75%.
Determine if $25 sufficent to cover the haircut with tax and a 15% tip.
Solution:
Take 4.75% of 20 then add it to 20. To do so we multiply 20 by the decimal value of 4.75. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 4.75/100
= 0.0475
= (0.0475)($20)
=$.95
= $20 + $.95
= $20.95
Add the 15% tip to 20.95.
= 15/100
= 0.15
= (0.15)($20.95)
=$3.14
= $20.95 + $3.14
= $24.1
Final answer:
$25 is sufficient for the haircut.
