1 answer:
The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00
Step-by-step explanation:
Let,
Cost of one kilogram of cinnamon red hots = x
Cost of one kilogram of gummy bears = y
According to given statement;
3x+y=21 Eqn 1
3x+3y=39 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 2
Putting y=9 in Eqn 1
Dividing both sides by 3
The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00

The answer is B) The initial number of bacteria is 57, and the growth rate is 31% per hour.
The expression shown is an <em>exponential expression</em>. An exponential expression usually takes the form , as this one does. A represents the <em>initial value</em>, in this case-the initial number of bacteria. B represents the <em>growth rate</em>. When it is an increasing growth rate, it will begin with 1, because it will have everything it had before, plus the percent increase, the decimal portion. In this case, a=57, and b=0.31.
Hope this makes sense!
