Astore sells 3 ears of corn for $1 they round prices to the nearest cent. tell whether you would describe the relationship between cost and number of ears of corn as proportional relationship. justify your answer. table: ears of corn: 1 2 3 4 amount charged: 0.33 0.67 1.00 1.34

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.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
