Kim will pay $25 because 30-5=25
Emily will pay $22.50 because 25•.90=22.5
25-22.5=2.5
the difference is $2.50
Y=2000*
2200=2000*
<span>
so,
y at t=8 is 2000*(</span><span>
)^8
y = 2000(22/20)^2=2000*1.21=</span><span>2420 thats the answer i hope.</span>
The decimal is .39024..., or rounded to percent it is 39%

Answer:
25, 36, 49
Step-by-step explanation:
Start with a definition of perfect squares. Basically, they're the result of a number multiplied by itself. 2*2, or 2² = 4, which is a perfect square. 3*3, or 3² = 9, and so on. You can keep listing these until you get inside the interval you want (from 22 to 50).
4² = 16
5² = 25 ... so now we're where we want to be!
6² = 36 ... still good
7² = 49 ... that's lower than 50 still
8² = 64 ... and now we're over our limit, so 8 doesn't do the job for us.
The only perfect squares matching your criteria are 25, 36, and 49.
