You take a group of 20 people going to the movies. kids' tickets
cost $ 4.- each, and adults tickets $ 6.- each. your total cost is $
96.- . the number of kids in your group is
hint: set up and solve a linear system.

The number of kids in group is 12

Solution:

Let "k" be the number of kids

Let "a" be the number of adults

Cost of 1 kid ticket = $ 4

Cost of 1 adult ticket = $ 6

You take a group of 20 people going to the movies

Therefore, we frame a equation as:

number of kids + number of adults = 20

k + a = 20 ----------- eqn 1

Your total cost is $  96

Therefore, we frame a equation as:

number of kids x Cost of 1 kid ticket + number of adults x Cost of 1 adult ticket = $ 96

4k + 6a = 96 ---------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

k = 20 - a ------ eqn 3

Substitute eqn 3 in eqn 2

4(20 - a) + 6a = 96

80 - 4a + 6a = 96

80 + 2a = 96

2a = 16

Substitute a = 8 in eqn 3

k = 20 - 8

Thus number of kids in group is 12

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
