Rose would be saving 50 dollars after 10 months. So you know that Rose got $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.
You would have to make 465=1550-7 1/2 x and find x Subtract 1550 from both sides -1085=-7 1/2x Divide -7 1/2 on both sides And the answer is 144 2/3 Sorry about ur bad luck
