'Of' in mathematics means 'multiply'. Change the 25% to a decimal by moving the percent sign two places to the left.

25% becomes .25.

Mutliply: .25 * 42 or 1/4 * 42

Answer: 10.5

At the game Spectators can buy a large popcorn (16 oz cup) for $1.12 or a small popcorn (12 oz cup) for $0.96 which Popcorn opti

shtirl [24]

The unit ratio is defined as the total cost divided by the number of oz.

So, the large popcorn has a unit cost of

$\dfrac{1.12}{16}=0.07$

meaning that 1oz of pop corn costs 7 cents.

Similarly, the small popcorn has a unit cost of

$\dfrac{0.96}{12}=0.08$

meaning that 1oz of pop corn costs 8 cents.

So, the large popcorn has a lower unit rate.

At the start of the year, 15 chameleons were introduced into a zoo. The population of chameleons is expected to grow at a rate o

bearhunter [10]

Answer:

option-B

Step-by-step explanation:

We are given

At the start of the year, 15 chameleons were introduced into a zoo

so, $P_0=15$

The population of chameleons is expected to grow at a rate of 41.42% every year

so, r=0.4142

and x represents the number of years since the chameleons were introduced into the zoo

now, we can set equation to find total population

and we get

$P(x)=P_0(1+r)^x$

now, we can plug values

$P(x)=15(1+0.4142)^x$

$P(x)=15(1.4142)^x$

Average rate of change between 2 years and 4 years:

we can use formula

$A_1=\frac{P(4)-P(2)}{4-2}$

now, we can plug values

$A_1=\frac{15(1.4142)^{4}-15(1.4142)^{2}}{4-2}$

$A_1=14.99914$

Average rate of change between 4 years and 6 years:

we can use formula

$A_2=\frac{P(6)-P(4)}{6-4}$

now, we can plug values

$A_2=\frac{15(1.4142)^{6}-15(1.4142)^{4}}{6-4}$

$A_2=29.99770$

Average rate of change between 6 years and 8 years:

we can use formula

$A_3=\frac{P(8)-P(6)}{8-6}$

now, we can plug values

$A_3=\frac{15(1.4142)^{8}-15(1.4142)^{6}}{8-6}$

$A_3=59.99425$

now, we will check each options

option-A:

we can see that

$A_3-A_2=30$

So, this is FALSE

option-B:

$A_1=\frac{1}{2}A_2$

So, this is TRUE

option-C:

This is FALSE

option-D:

we got

$A_1=\frac{1}{2}A_2$

so, this is FALSE
