X + y = 51
x - y =15
2x = 66
x = 33
33 + y = 51
y = 18
81% of 2,500 is 2025, so that’s how many people would have a cell phone.
This mean for every 2 boys there are 3 girls 12 divided by 2 is 6 so you have todo 6*3 which is 18
Let's assign a variable x to the number of multiples for each pound of dry mix and water. With that being the said, the question for finding the total pounds would be:
Total pounds = x*Pounds of dry mix + x*Pounds of water
Total pounds = 60x + 8x = 68x = 14 + 1/6 = 85/6
x = 85/6 / 68
x = 5/24
Thus, the pounds of dry mix is 60*5/24 = 25/2 lbs, while the pounds of water is 8*5/24 = 5/3 pounds.
