Question

jennifer now earns $250 more than three times the salary she earned as a cashier. If she now earns $10,300 how much did she earn as a cashier?

thank you

Answer 1

Let x = her cashier's salary.

3x + 250 = 10,300

Answer 2

3350

Answer 3

$3350

Answer 4

Let cashiers salary be x

Cashiers salary = x

3x+250=10300 ( cuz she earns 10300 now )

3x =10300-250
3x= 10050/3

x= 3350
