19/5=p/3-36/5
Convert the decimals into fractions
15 x 19/5=(p/3-36/5) x 15
Multiply both sides by 15
57=5x-108
5x-108+108=57+108
Add 108 to both sides
5x=165
X=33

Answer:
If he spends $120 dollars a month, and he cut's that down to $50 a month, we should create a pattern to visualize the months.
Step-by-step explanation:
120- 50= 70 ($70 saved each month)
Month 1- $70 saved total
Month 2- $140 saved total
Month 3- $210 saved total
Month 4- $280 saved total
Month 5- $350 saved total
Month 6- $420 saved total
It takes 6 months to get 400 saved. We could also divide to get
5.714285, but it would takes 6 months before reaching the goal. :)
