Answer:
Step-by-step explanation:
x - represents 1 point shots
(54 - x) - represents 2 point shots
x + 2(54 - x) = 89
x + 108 - 2x = 89
-x + 108 = 89
x = 19 (1 point shots)
54-x = 35 ( 2 point shots)
Test:
19 + 35 = 54 (total shots)
19 x 1 = 19
35 x 2 = 70
70 + 19 = 89 points
Year 1990, dolphins were 243,000
2.3% of 24300
= ( 2.3 / 100 ) * 243000
= ( 0.023 ) * 243000
= 5589
So every year, the population of dolphins decrease by 5589.
Now from 1990 to 2030 will be
= 2030 - 1990
= 40 years
Therefore, for a year = 5589 decrease
For forty years, it will be
= 40 * (5589)
= 223560 dolphins will be lost after forty years
The remaining ones
= 243000 - 223560
= 19440 dolphins will be left
