Answer:

Step-by-step explanation:

Using the definition

n $C_{r}$ = $\frac{n!}{r!(n-r)!}$

where n! = n(n - 1)(n - 2).... × 3 × 2 × 1

Then evaluating numerator and denominator

10 $C_{3}$

= $\frac{10!}{3!(7!)}$

= $\frac{10(9)(8)(7)(6)(5)(4)(3)(2)(1)}{3(2)(1)(7(6)(5)(4)(3)(2)(1)}$

Cancel 7(6)(5)(4)(3)(2)(1) on numerator/ denominator, leaving

= $\frac{10(9)(8)}{3(2)}$ = $\frac{720}{6}$ = 120

-------------------------------------------------------------------------------------

6 $C_{4}$

= $\frac{6!}{4!(2!)}$

= $\frac{6(5)(4)(3)(2)(1)}{4(3)(2)(1)(2)}$

Cancel 4(3)(2)(1) on numerator/ denominator, leaving

$\frac{6(5)}{2}$ = $\frac{30}{2}$ = 15

-------------------------------------------------------------------------------------

Dividing numerator by denominator gives

$\frac{120}{15}$ = 8 → A

Marcus is buying 10 gift bags for his birthday party. He will choose items to put in the bags and then pay an additional charge

adoni [48]

10*0.75 + 10*x $\leq$ 50
This is how our inequality looks where x represents items cost per bag.

10*x $\leq$ 42.5

x $\leq$ 4.25.

Marcus can spend $4.25 at most per bag.
The money he spent on buying bags we can calculate right away because we know how much one bag costs and how many bags he bought.
