Betty saves 3 times as much as Ann. Charles save 390 less than Ann.. If Betty saves save 1330 more than Charles. how much does Charles save?

80

Step-by-step explanation:

We let x be Ann's savings.

Betty saves 3 times as much as Ann.

This implies that Betty's savings in terms of x

Charles save 390 less than Ann.

This implies Charles savings

Betty saves 1330 more than Charles.

This implies that when we deduct Charles savings from Betty's we have to get 1330.

Mathematical equation for the problem:

Expand :

Subtract 390 from both sides.

Divide through by 2

Hence Charles saving is

24.0345 ft < the height of the building
