A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.
