Adding p = -1

$- 38( - 1) {}^{2} - 78( - 1) \\ - 38 \times 1 - ( - 78) \\ ( - 38) - ( - 78) \\ - 38 + 78 \\ = 40$

There are 1200 students at a school.

const2013 [10]

Answer:

The number of boys that have school dinners is 381.

Step-by-step explanation:

First, we need to find how many students have school dinners:

$SD = 1200*0.62 = 744$

The percent of girls that have school dinners:

$\%SD_{g} = 100\% - 45\% = 55\%$

Now, we need to find the number of boys (b) and girls (g) at a school:

$g = 1200*0.55 = 660$

$b=1200 - 660 = 540$

Hence. the percent of boys that have school dinners is given by:

$SD = g*\%SD_{g} + b*\%SD_{b}$

$\%SD_{b} = \frac{SD - g*\%SD_{g}}{b} = \frac{744 - 660*0.55}{540} = 0.706$

$\%SD_{b} = 70.6\%$

Finally, the number of boys that have school dinners is:

$B = 540*0.706 = 381$

Therefore, the number of boys that have school dinners is 381.

I hope it helps you!
