00:06

soda served ten people writing equation to determine how many

00:09

bottles of soda x are needed to serve thirty five

00:13

people Well these party planners are optimistic They seem to

00:18

think that people consume soda at a constant rate at

00:22

a little get together Ten people happily guzzled four bottles

00:24

of soda and they use this ratio to decide how

00:27

many bottles of soda x to purchase for a party

00:30

of thirty five people Well whether it's true or not

00:33

the theory is that the ratio of sodas purchased people

00:36

present is the same in each case So let's just

00:39

write it out is a word equation when you get

00:40

confused on these questions It's a really easy way to

00:43

at least get started You got number of soda bottles

00:45

is to the number of people right that's the ratio

00:48

while the values from the ten person get together belong

00:51

in one fraction and the values of the thirty five

00:54

person shindig going the other right So we have four

00:57

is two ten as Acts or something is toe 30

01:00

five Right So khun reduce it down a bit too

01:02

Is to five as x is the thirty five Well

01:05

think about it The equation to determine the amount of

01:08

soda needed for thirty five people is this Two Fifty

01:11

equals x over thirty five and well that's answer See 00:01:15.24 --> [endTime] and well we're done Bye
