The table shows the number of calories in different numbers of apples.

Number of apples 3 5 8
Number of calories 195 325 520
How many calories are in 9 apples?

Answer 1

585 calories are in 9 apples

Explanation:

Number of apples : 3 || 5 || 8

Number of calories: 195 || 325 || 520

Find the unit rate:

`(y2-y1)/(x2-x1)`

`(325-195)/(5-3)`

`(130)/(2)`

`65`

Find equation:

y - 325 = 65( x -5)

y = 65x - 325 +325

y = 65x .....this is the equation to find any number of calories.

put x as 9 here:

y = 65x

y = 65(9)

y = 585 calories
