Question

Eight bottles of soda and four bags of chips cost $16. Six bottles of soda and 7 bags of chips cost $14. How much does a bottle of soda cost? How much does a bag of chips cost?

Answer 1

Answer: soda 1.75 dollars and chips is 0.50 dollars

Step-by-step explanation:you have to work out the question like a simultaneous equation so key s=soda and c=chips

8s+4c=16

6s+7c=14 make chips equal

56s+28c=112

24s+28c=56 Take the equations away

32s=56

S=56\32

S=7/4

S=1.75 sub that answer in the first equation

8*1.75=14

14+4c=16

4c=2

C=0.5
