Question

Emilia is shopping for fresh produce at a farmers’ market. She bought a watermelon for $5, and she also wants to buy peppers. Each pepper is $0.75. Let t represent the total cost of the produce and n be the number of peppers bought. Determine which variable is independent and which is dependent, and write an equation that models the situation. Then, make a table to show the cost for 1 to 5 peppers.

Answer 1

Answer and Step-by-step explanation:

watermelon = $5

Each pepper = $0.75

t = total cost of the produce

n = number of peppers bought

t depends on n, because we can only know the price if we know how many peppers were bought

t = 5 + 0.75n

+---+------------+------+

| n | 5 + 0.75n | t |

+---+------------+------+

| 1 | 5 + 0.75*1 | 5.75 |

+---+------------+------+

| 2 | 5 + 0.75*2 | 6.50 |

+---+------------+------+

| 3 | 5 + 0.75*3 | 7.25 |

+---+------------+------+

| 4 | 5 + 0.75*4 | 8 |

+---+------------+------+

| 5 | 5 + 0.75*5 | 8.75 |

+---+------------+------+
