Part 1) option A

Part 2) Table 3 see the attached figure

Step-by-step explanation:

Part 1)

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

The table represent a direct variation

The unit rate for one gallons of gasoline is equal to the constant of proportionality k

Let

x-----> the number of gallons

y-----> the price

so

For ,

Find the value of k

Part 2)

Let

x------> string instruments

y------>  percussion instruments

table 1

the ratio is equal to

table 2

the ratio is equal to

table 3

the ratio is equal to

table 4
