Problem

Gabriela has dinner at a cafe and the cost of her meal is $\$45.00$dollar sign, 45, point, 00. Because of the service, she wants to leave a $15\%$15, percent tip.

What is her total bill including tip?

$\$\$dollar sign, space

Hint #11 / 5

The tip amount is equal to $15\% \times \green{\$45.00}$15, percent, times, start color #28ae7b, dollar sign, 45, point, 00, end color #28ae7b.

We can find the tip by first calculating a $\purple{10\%}$start color #9d38bd, 10, percent, end color #9d38bd tip and a $\pink{5\%}$start color #ff00af, 5, percent, end color #ff00af tip, and then adding those two numbers together.

Hint #22 / 5

To calculate a $\purple{10\%}$start color #9d38bd, 10, percent, end color #9d38bd tip, move the decimal point in $\green{\$45.00}$start color #28ae7b, dollar sign, 45, point, 00, end color #28ae7b one place to the left.

$\purple{10\%} \times \green{\$45.00} = \purple{\$4.50}$start color #9d38bd, 10, percent, end color #9d38bd, times, start color #28ae7b, dollar sign, 45, point, 00, end color #28ae7b, equals, start color #9d38bd, dollar sign, 4, point, 50, end color #9d38bd

Hint #33 / 5

To calculate a $\pink{5\%}$start color #ff00af, 5, percent, end color #ff00af tip, divide the $\purple{10\%}$start color #9d38bd, 10, percent, end color #9d38bd tip amount in half.

$\pink{5\%} \times \green{\$45.00} = \purple{\$4.50} \div 2 = \pink{\$2.25}$start color #ff00af, 5, percent, end color #ff00af, times, start color #28ae7b, dollar sign, 45, point, 00, end color #28ae7b, equals, start color #9d38bd, dollar sign, 4, point, 50, end color #9d38bd, divided by, 2, equals, start color #ff00af, dollar sign, 2, point, 25, end color #ff00af.

Hint #44 / 5

Adding the two amounts together gives us $\purple{\$4.50} + \pink{\$2.25} = \blue{\$6.75}$start color #9d38bd, dollar sign, 4, point, 50, end color #9d38bd, plus, start color #ff00af, dollar sign, 2, point, 25, end color #ff00af, equals, start color #6495ed, dollar sign, 6, point, 75, end color #6495ed.

Hint #55 / 5

The total bill is the cost of the meal plus the tip.

$\green{\$45.00} + \blue{\$6.75} = \$51.75$start color #28ae7b, dollar sign, 45, point, 00, end color #28ae7b, plus, start color #6495ed, dollar sign, 6, point, 75, end color #6495ed, equals, dollar sign, 51, point, 75.
