12 boys. 7 * 3 is 21. 21 girls. 4*3 is 12. 12 boys 21 girls
Answer:
It will take about 35.439 years to triple.
Step-by-step explanation:
Recall the formula for continuously compounded interest:

where "A" is the total (accrued or future) accumulated value, "r" is the rate (in our case 0.031 which is the decimal form of 3.1%), "P" is the principal, and "t" is the time in years (our unknown).
Notice also that even that the final amount we want to get is three times $48,000. So our formula becomes:

Now,in order to solve for "t" (which is in the exponent, we use logarithms:

Rational numbers.
The grocery store will have a whole number of half gallons =>
number of gallons = n * [1/2] , where n = ∈ N
That means that the number of gallons ∈ Z+ and 0.
Then the answer is the option A. rational number.
