I Nisa buy dollars worth of stock and gained $25 per year Kevin bad for hundred dollars worth of stock in the last $35 per year

alisha [4.7K]

Answer: x= 5 years and y = $225

Step-by-step 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,

$100+25x=400-35x\\\\25x+35x=400-100\\\\60x=300\\\\x=\frac{300}{60}\\\\x=5$

so, For x= 5 years,

Their income of Nisa and loss of Kevin will be

$y=100+25x\\\\y=100+25\times 5\\\\y=100+125\\\\y=\$225$
