X = smallest; x + 2 = middle, and x + 4 = largest
x + 2(x+2) = 20 + x + 4
x + 2x + 4=24 +x
3x + 4 = 24 + x
2x = 20
x = 10
so the three integers are 10, 12, and 14

Answer: Tara earned $775 from her summer job.
Step-by-step explanation:
Let x represent the amount of money that Tara earned from her summer job.
Lewis earned $1800 from his summer job at the grocery store. This is $250 more than twice what his friend Tara earned. The equation would be
2x + 250 = 1800
Subtracting 250 from the left hand side and the right hand side of the equation, it becomes
2x + 250 - 250 = 1800 - 250
2x = 1550
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 1550/2
x = 775
