Question

@vocaloid
Elsa has a job transporting soft drinks by truck. Her truck is filled with cans that weigh 14 ounces each and bottles that weigh 70 ounces each. There is a combined total of
940 cans and bottles in her truck.Let x be the number of
14-ounce cans in her truck. Write an expression for the combined total weight (in ounces) of the cans and bottles in her truck.

Answer 1

this is very similar to the last problem, any ideas on where to start?

Answer 2

no idea

Answer 3

try and look over the last problem and apply the same rule

Answer 4

hint: our expression will look something like this:

(number of 14 oz cans)*14+ (number of 70 oz bottles)*70

number of 14 oz cans = x
total number of cans + bottles = 940

keep going from here

Answer 5

I still dont get it

Answer 6

@Vocaloid

Answer 7

number of cans = x
number of cans + bottles = 940
number of bottles = ____

fill in the blank

Answer 8

it doesnt say how many bottles

Answer 9

I know that, you need to figure out how many bottles there are

Answer 10

(hint: your answer won't be a number, it'll be an expression using the variable x)

Answer 11

i know

Answer 12

number of cans = x
number of cans + bottles = 940

number of bottles = 940 - x

does that make sense so far?

Answer 13

total weight (in ounces)
=14x70−940x

Answer 14

14x+70(940-x)

Answer 15

yes! good job

14x+70(940-x) is the answer
