A store sells 3 ears of corn for $1 they round prices to the nearest cent.

Ears of corn:           1         2         3      4

Amount charged: 0.33  0.67    1.00   1.34

1 ear of corn for $0.33

2 ears of corn for = rounded to $0.67.

3 ears of corn for = rounded to $1.

The answer will be:

Yes; the relationship between cost and number of ears of corn is proportional.

Even though the rates in the table are not constant per ear of corn, but there is a constant rate for every 3 ears of corn.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
