Answer 1

Answer: x= 5 years and y = $225

Explanation:

Since we have given that

Amount Nisa gained per year = $25

Amount Kevin lost per year = $35

According to question,

`y=100+25x\\\\and\\\\y=400-35x`

so, it becomes,

`100+25x=400-35x\\\\25x+35x=400-100\\\\60x=300\\\\x=(300)/(60)\\\\x=5`

so, For x= 5 years,

Their income of Nisa and loss of Kevin will be

`y=100+25x\\\\y=100+25* 5\\\\y=100+125\\\\y=\$225`
