Question

While shopping for clothes, Jocelyn spend $80 less than three times what Tracy spent. Jocelyn spend $10. Right and solve an equation to find out how much Tracy spent. Let X represent how much Tracy spent.

Answer 1

If Daniel spent x
x dollars, then Tracy spent 3x−8
3x−8 dollars. Since Tracy spent $10, we can write the equation:

3x−8=10
3x−8=10

Solve for x
x. Add 8 to both sides:

3x=18
3x=18

Divide both sides by 3:

x=6
x=6

So, Daniel spent $6.

Answer 2

Tracy = x
Jocelyn = 3x - 80
When y = 10
y = 3x - 80
10 = 3x - 80
90 = 3x, x = 30
Solution: Tracy spent $30
