Can someone explain 11 and 12 plz step by step. I have to explain how the expenses add up or how much salary they earned and how much money they gave away?

Step-by-step explanation:

11.  Pay is $150 for 3 days

4.25*3=12.75

2.50*3=7.50

12.75+7.50=20.25 for expenses.  150-20.25= 129.75 which is over the 125.00 per week needed.

12. 225 per week

Abe: 15.75+12.50= 28.25 per week expenses. 225-28.25= 196.75 left over

Chandra: 3.50*3=10.50

5.25*3=15.75

15.75+10.50=26.25 expenses. 26.25-225= 198.75 left over

Chandra has more $$ left over

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

25% is the answer
