At the deli Jimmy bought $17 worth of food. The tax on the bill was 6% and he left an 18% tip on the pre-tax amount.
Which expression can be used to calculate the tip Jimmy left?
Responses
A .18(17).18(17)
B .18[17 +(.06)(17)].18[17 +(.06)(17)]
C .18 (17 + .06).18 (17 + .06)
D 18[17 + 6(17)]18[17 + 6(17)]
E .18(.06).18(.06)
The expression that can be used to calculate the tip Jimmy left is:
B) .18[17 +(.06)(17)].18[17 +(.06)(17)]
To calculate the tip Jimmy left, we need to find the pre-tax amount and then calculate 18% of that amount.
Step 1: Calculate the pre-tax amount
The pre-tax amount is the original bill amount minus the tax. In this case, the bill amount is $17 and the tax is 6%. To find the tax amount, we can calculate 6% of $17 by multiplying $17 by 0.06.
Tax amount = $17 * 0.06 = $1.02
Now, we can find the pre-tax amount by subtracting the tax amount from the bill amount:
Pre-tax amount = $17 - $1.02 = $15.98
Step 2: Calculate the tip amount
To calculate the tip amount, we need to find 18% of the pre-tax amount. We can calculate 18% of $15.98 by multiplying $15.98 by 0.18.
Tip amount = $15.98 * 0.18 = $2.88
So, the expression that can be used to calculate the tip Jimmy left is:
B. .18[17 +(.06)(17)].18[17 +(.06)(17)]
The expression that can be used to calculate the tip Jimmy left is:
B. .18[17 + (.06)(17)].
