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
