It’s B.
Distribute the 7a and multiply it with the 3a and -4 a. With the exponents you add them.
The doubling time is time it takes for a population to double in size/value. ... When the relative growth rate (not the absolute growth rate) is constant, the quantity undergoes exponential growth and has a constant doubling time or period, which can be calculated directly from the growth rate.
The decrease is 35c
Q= X/100 of $1.37 = 0.35
1.37x/100 = 0.35
1.37x = 35 then divide each side by 1.37
Result is 25.5474453 percent, round up to nearest tenth.
Answer is 25%
Answer: 29.75%
Step-by-step explanation:
X/100 *80.33=23.90
80.33x=2390
X=2390/80.33 = 29.75
