There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.
igor_vitrenko [27]

Answer:

The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =

Cost(c)= 1/8($15.68 × 6)

The cost (c) if you buy 6 jars of jellyfish jelly is $11.76

Step-by-step explanation:

There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.

The proportion is given as:

Number of jars of Jellyfish/Cost of the Number of jar of Jellyfish

Hence:

8/$15.68 = 6/c

We Cross Multiply

8 × c = $15.68 × 6

c = $15.68 × 6/8

c = $11.76

Therefore,

The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =

Cost(c) = 1/8($15.68 × 6)

The cost (c) if you buy 6 jars of jellyfish jelly is $11.76
