Abigail: x

Jake: 3/4x

---

Make their expressions add up to 140 in an equation.

(x) + (3/4x) = 140

Combine like terms.

1 3/4x = 140

Divide both sides by 1 3/4.

x = 80

Plug 80 for x into Jake and Abigail's expressions.

Jake: 3/4(80) = 60

Abigail: (80) = 80

---

Jake earned $60 and Abigail earned $80.

Let's represent Jake with the variable 'j' and Abigail with the variable 'a':

j = 3a/4

j + a = 140

j = -a + 140

3a/4 = -a + 140

3a = -4a + 560

7a = 560

a = 80

Abigail earned $80 and Jake earned $60
