Answer:
1. 4 months.
2. Makes jacket more expensive
Explanation:
You get paid twice a month which means that you can save:
= 45 * 2
= $90 per month
The jacket is $350 so it will take:
= 350/90
= 3.88
= 4 months to afford it.
4 * 90 = $360
Assuming there is inflation in those 4 months, it will make the price of the jacket rise and if the inflation rate is such that the price rises past $360, you will be unable to afford the jacket at that point in time and will have to wait to be paid again.
