Q: Maria's monthly salary is $2000. 20% of her salary goes to paying tax, and 5% goes to insurance. Also, a quarter of the money left after the deductions is spent on utility bills. How much money does Maria have after the deductions and utility bills payment?
A: Maria's deduction for tax is 2000 x 20% = $400. Her deduction for insurance is 2000 x 5% = $100. Maria's total deductions is $400 + $100 = $500. After the deductions, Maria has only $2000 - $500 = $1500 left from her salary. Then, Maria pays $1500 / 4 = $375 for the utility bills. So, Maria has $1500 - $375 = $1125 after the deductions and utility bills payment. The answer is 1125.

Q: Jennifer purchased 40 cans of milk at the store before meeting her classmate Mark, who was also buying milk. Jennifer bought 6 additional cans for every 5 cans Mark bought. If Mark purchased 50 cans, how many cans of milk did Jennifer bring home from the store?
A:
If Mark bought 50 cans of milk, the number of times Jennifer added 6 cans for every 5 that Mark bought is 50 / 5 = 10 times. The total number of additional cans she bought is 10 * 6 = 60 cans. If she initially had 40 cans, she went home with 40 + 60 = 100 cans of milk. The answer is 100.
