Studdy Solution

STEP 1

1. The cost of a standard haircut is \$35.
2. The tip percentage is 20%.
3. We need to calculate the tip amount based on the given percentage.

STEP 2

1. Define the variables.
2. Calculate the tip amount.

STEP 3

Let the cost of the haircut be denoted as C=$35 C = \$35 .

STEP 4

Let the tip percentage be denoted as T=20% T = 20\% .

STEP 5

Convert the percentage to a decimal for calculation purposes.
T=20%=0.20 T = 20\% = 0.20

STEP 6

Calculate the tip amount by multiplying the cost of the haircut by the decimal form of the tip percentage.
Tip Amount=C×T=$35×0.20 \text{Tip Amount} = C \times T = \$35 \times 0.20

STEP 7

Perform the multiplication to find the tip amount.
Tip Amount=$35×0.20=$7 \text{Tip Amount} = \$35 \times 0.20 = \$7
The tip amount for a standard haircut is:
$7\boxed{\$7}
