The amount of blue color in the green paint is an illustration of ratios and proportions.

Cheryl's green paint has more blue color

The proportion of blue color is calculated as:

\mathbf{Proportion = \frac{Blue}{Blue+ Yellow}}

So, we have:

\mathbf{Cheryl= \frac{16}{16+ 24}}

\mathbf{Cheryl= \frac{16}{40}}

\mathbf{Cheryl= 0.40}

Express as percentage

\mathbf{Cheryl= 40\%}

\mathbf{Rodney= \frac{6}{6+ 10}}

\mathbf{Rodney= \frac{6}{16}}

\mathbf{Rodney= 0.375}

Express as percentage

\mathbf{Rodney= 37.5\%}

By comparison: 40% >37.5%

Hence, Cheryl's green paint has more blue color

Samantha sends her son, Barry, to a preschool center on certain days. The cost of preschool is $45 per day along with a fixed mo
MAXImum [283]

Answer:

<h3><em>D. 880 = 45d + 70; 18 days.</em></h3>

Step-by-step explanation:

We are given fixed monthly charge = $70.

The cost of preschool per day = $45.

Number of days = d.

Total cost of d days = cost per day × number of days + fixed monthly charge.

Therefore, we get equation

880 = 45×d+70

<h3>880 = 45d +70.</h3>

Now, we need to solve the equation for d.

Subtracting 70 from both sides, we get

880-70 = 45d +70-70

810=45d

Dividing both sides by 45, we get

\frac{810}{45} =\frac{45d}{45}

18=d.

Therefore,<em> 18 days Barry attended preschool last month.</em>

<em>Therefore, correct option is D option.</em>

<h3><em>D. 880 = 45d + 70; 18 days.</em></h3>
