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 350=12(x+20) to represent the situation. Solve the equation for x.

Respuesta :

In this case, x is the amount more he needs to save per month

350=12(x+20)
distribute
350=12x+240
minus 240 both sides
110=12x
divide both sides by 12
9.166666=x

needs to save about $9.17 more per  month or 29.17 permonth

Answer:

x = 55/6

Step-by-step explanation:

Divide both sides by 12:

[tex]\frac{350}{12} = \frac{12( + 20)}{12}[/tex]

Simplify:

175/6= x + 20

Subtract 20 from both sides and flip:

x = [tex]\frac{55}{6}[/tex]
