Answer:
[tex]\$60.35[/tex]
Step-by-step explanation:
step 1
Find the total amount of money worked
Multiply 6.5 hours by the rate $11.50 / hour.
[tex]6.5(11.50)=\$74.75[/tex]
step 2
Find the total cost of the dinner
Remember that
[tex]100\%+20\%=120\%=120/100=1.2[/tex]
so
the cost of the dinner plus the tip is equal to
[tex]\$12(1.2)=\$14.4[/tex]
step 3
Find the amount of money left
Subtract the total cost from the total amount of money
so
[tex]\$74.75-\$14.4=\$60.35[/tex]
