Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
Now, to find the cost in 3 years, use x as 3.
Which is simplified to
y=$80.19

Answer:
35 dogs
Step-by-step explanation:
We can simplify the ratio 49:28 by dividing by 7
The new ratio is 7:4 which is easier to work with.
It says there are 20 cats so we know that for every 4 cats there are 7 dogs
We simply multiply 20 by 7/4
20 x 7/4 = 35 so there are 35 dogs
