Question

Spongebob starts with $50 and saves $6 each week. Patrick starts with $20 and saves $12 each week. When will they both have the same amount of money? How much money will they have?

Answer 1

Answer:

At $80 they will become same

Step-by-step explanation:

Let the money that they become same be x

Then,

50+6x = 20+ 12x

50+6x-20-12x=0

30-6x = 0

30 = 6x

x = 30/6

= 5

Then,

50+6x = 20+ 12x

50+(6×5) = 20 + (12×5)

50+30 = 20+60

80 = 80

Therefore at $80 they become same
