Answer 1

Until 15 days, Spiderman has more money than Batman.

Explanation:

Giving the following information:

Spiderman has $350 in his account and is earning $25 each day. Batman has $200 in his account and earns $35 per day.

First, we need to structure the total income formulas:

Spiderman= 350 + 25x

Batman= 200 + 35x

x= number of days

Now, we equal the formulas and isolate x:

350 + 25x = 200 + 35x

150= 10x

150/10= x

15 =x

Until 15 days, Spiderman has more money than Batman.
