Answer:
55 pages
Step-by-step explanation:
Knowing that the <em>book holds 600 cards and 6 cards/page</em>, we can tell that there are <em>100 pages</em>.
From that, we know that 45% are empty, which means <em>55% of all of the pages have cards</em>.
55% of 100 is 55. Therefore, 55 pages have baseball cards.

The maximum rate, r, that the scuba diver may descend is r ≤ 12.6
A linear equation is in the form:
y = mx + b;
where y, x are variable, m is the slope of the line and b is the y intercept.
Let r represent the rate. Since the initial depth is 15.2 feet below sea level, hence b = -15.2. Also, it reaches a depth no more than 46.7 feet below sea level within 2 1/2 (2.5 minutes). therefore:
2.5r - 15.2 ≤ -46.7
2.5r ≤ -31.5
r ≤ -12.6
r ≤ 12.6 (descending)
The maximum rate, r, that the scuba diver may descend is r ≤ 12.6
