Answer:
C(x)= 19x+1260
Step-by-step explanation:
For 90 sweatshirts
2970=90a+b
For 280 sweatshirts
6580=280a+b
Subtracting equation 1 from 2 then
6580-2970= (280x-90x)+b-b
3610=190a
x=3610/190=19
2970=90(19)+b
b=2970-90(19)=1260
Therefore, the equation will be
C(x)= 19x+1260

Step-by-step explanation:
S.I. = Rs. 1080
Time = 2 years
Principal = SI.*100/P * T
= 1080*100/9000*2
=1,08,000/18,000
= 6%
15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
