Answer:
C. 300=60+30w
Step-by-step explanation:
Given:
Price of television-$300
Initial Payment-$60
Weekly payments-$30
Let weekly payments be w:
The initial payment plus the weekly installments should be equivalent to the television price:

The number of weekly payments is 8 weeks and the equation to solve for w is
300=60+30w
A- solve bracket first so
3/4 + 2/9 +5/12 then multiply by 3.6 = 5
do the same with the rest and u get
A=5
B=1
C=15
D=3

So this is what's known as a combination. a combination is a group where the order does not matter. to solve a combination, you use this equation:
n! / (r! *(n-r)!)
n is the total number of objects being sorted (8)
r is the group you need to sort them into (4)
(i know it's 2 groups of 4 but if you solve this for 1 group, the other group is automatically made of the remaining kids)
definition of !:
a number with a ! means 1*2*3...*that number (so that number multiplied by every number smaller than it all the way to one)
so we put 8 and 4 in this equation:
8! / (4! *(8-4)!)
simplify:
8! / *(4! 4!)
multiply out:
(8*7*6*5*4*3*2*1) / (4*3*2*1 * 4*3*2*1)
and put that in your calculator
you will get 70
your answer is 70
