Question

You work for 6.5 hours at a rate of $11.50 / hour.

You buy dinner that costs $12, and give a 20% tip.

How much money are you left with?

Answer 1

`\$60.35`

Explanation:

step 1

Find the total amount of money worked

Multiply 6.5 hours by the rate $11.50 / hour.

`6.5(11.50)=\$74.75`

step 2

Find the total cost of the dinner

Remember that

`100\%+20\%=120\%=120/100=1.2`

so

the cost of the dinner plus the tip is equal to

`\$12(1.2)=\$14.4`

step 3

Find the amount of money left

Subtract the total cost from the total amount of money

so

`\$74.75-\$14.4=\$60.35`
