If prices increase at a monthly rate of 3.7%, by what percentage do they increase in a year?

Since there are 12 months in a year, and it increases at a rate of 3.7% every month, we can get the correct answer by multiplying 3.7% by 12.
3.7*12=44.4
It increased at a percentage of 44.4 each year.
Hope this helps!

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
