Question

3. A balloon with a small leak loses 0.5% of its volume each day. If it originally contained 40 liters of gas, what is the volume of the gas after one week?

Answer 1

40*0,995=39,8
39.8*0,995=39.601
39.601*0,995=39.402995
39.402995*0,995=39.205980025
39.205980025*0,995=39.0099501249
39.0099501249*0,995=38.8149003743
38.8149003743*0.995=38.6208258724
math isnt wrong but idk if this is how its done bcs this method looks kinda weird
