There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4. There are 180 students at Winthrop Midd
zavuch27 [327]

Given:

Total number of students at Colfax Middle School = 270

Ratio of boys to girls is 5:4.

Total number of students at Winthrop Middle School = 180

Ratio of boys to girls is 4:5.

The two schools hold a dance and all students from both schools attend.

To find:

The fraction of the students at the dance are girls

Solution:

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.

5+4=9

Number of boys =270\times \dfrac{5}{9}=150

Number of girls =270\times \dfrac{4}{9}=120

There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.

4+5=9

Number of boys =180\times \dfrac{4}{9}=80

Number of girls =180\times \dfrac{5}{9}=100

Now,

Total number of students in both schools = 270+180

                                                                = 450

Total number of girls in both schools = 120+100

                                                         = 220

The fraction of the students at the dance are girls is

\text{Required fraction}=\dfrac{\text{Total number of girls in both schools}}{\text{Total number of students in both schools}}

\text{Required fraction}=\dfrac{220}{450}

\text{Required fraction}=\dfrac{22}{45}

Therefore, the required fraction is \dfrac{22}{45}.

Keith bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $150 more than the desktop. He pa
ss7ja [257]

Answer: desktop = $1750, laptop = $1900

<u>Step-by-step explanation:</u>

Let x represent the cost of the desktop

then x + 150 is the cost of the laptop.

.07x + .055(x + 150) = 227

.07x + .055x + 8.25 = 227

.125x = 218.75

x = 1750

desktop (x) = $1750

laptop (x + 150) = $1750 + $150 = $1900
