Question

Jonathan and Evelyn had an equal amount of money at first. Jonathan spent $12 and Evelyn received $42 from her mother. Evelyn now has 4 times as much money as Jonathan. How much did Jonathan have at first?

Answer 1

Johnathon had $30 at first

Step-by-step explanation: Let's denote the initial amount of money that both Johnathon and Evelyn has as "x" dollars.

Johnathon spent $12, so he has (x-12) dollars left.

Evelyn received $42 from her mother, so she has (x+42) dollars.

Now, Evelyn has 4 times as much money as Jonathan does.

The equation is: x+42= 4 (x-12)

Now lets solve for x:

x+42=4x-48

42+48=4x-x

90=3x

Divide both sides by 3

90/3 = 3x/3

x=30

so Johnathan had $30 at first
