Cost of a bike Raylin wants to buy = $85
Money Raylin already has = $22
Money she needs :
Thus, money Raylin still needs = $63
Money she gets from doing one chore = 2.50
Number of chores the needs to do :
Thus, Raylin needs to do 25 chores to be able to buy the bike.
Therefore, the correct option is <em>(d) 25</em>
Answer:
top: 0.7, 0.9
bottom:7/10
0.7 = 7/10 because 7 is under tens. If it was 0.34 = 34/100 because 34 is in the hundereds. If it was 0.100 = 100/1000 because 100 is under the thousands. pls brainly trying to level up

2)16.02
Answer:
It will take 554 years
Step-by-step explanation:
Here, we want to estimate the time when t will be $50
We can rewrite the exponential equation as;
y = 200(1-0.0025)^t
In this case, y = $50 and we want to calculate t
so, we simply proceed to substitute the value 50 for y
we have this as ;
50 = 200(1-0.0025)^t
50/200 = (1-0.0025)^t
1/4 = 0.9975^t
0.25 = 0.9975^t
Take the natural logarithm of both sides
ln 0.25 = ln 0.9975^t
ln 0.25 = t ln 0.9975
t = ln 0.25 / ln 0.9975
t = 553.8 = 554 years
The bike will be $50 in 554 years
