Afully inflated basketball holds .34 cubic feet of air. the basketball is overinflated to hold .64 cubic feet of air. what is the percent of changes for the volume of air inside the baskeball?

88.2%

Step-by-step explanation:

The percent of change can be calculated by finding the difference between the two volumes and then dividing by the original volume.

0.64 - 0.34 = 0.3

0.3/.34 = 0.882

This is approximately an 88.2% increase in volume.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
