Answer 1

The price of 2 pounds of grapes i.e. $1.38 and the price of 8 pounds of grapes i.e. $5.52 are the missing values on the table.

Explanation:

The number of pounds and the total cost of grapes in dollars are given in the table.

From the table the price of grapes can be calculated as
`(4.83 - 2.76)/(7 - 4) = 0.69` dollars per pound.

Now, 2 pounds of grapes costs $(0.69 × 2) = $1.38

And, 3 pounds of grapes costs $(0.69 × 3) = $2.07

And, 6 pounds of grapes costs $(0.69 × 6) = $4.14

And, 8 pounds of grapes costs $(0.69 × 8) = $5.52

And, 11 pounds of grapes costs $(0.69 × 11) = $7.59

Therefore, the price of 2 pounds of grapes i.e. $1.38 and the price of 8 pounds of grapes i.e. $5.52 are the missing values on the table. (Answer)
