My mother is 4 years younger than 3 times my brother's age. If my brother is 12 years old, how old is my mother?
Fill in the blank:
years old

sis 12 years old

Step-by-step explanation:

age comes to 12+3=15 years and,

My brother's age would be 15+5=20 years

Therefore, my mother's age 20×2=40 years

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
