Maya is visiting her favorite candy store, the Sugar Spoon. The candy there is in self-serve bins, so Maya can pick out exactly the amount she wants. She has $30 to spend, and she wants to get a combination of saltwater taffy that costs $9 per pound and chocolate that costs $12 per pound.%0D%0AWhich pairs (t,c) represent possible amounts of taffy and chocolate, in pounds, that Maya could buy?

1 answer

Let t be the amount of taffy in pounds and c be the amount of chocolate in pounds. Maya wants to spend a total of $30, so the equation is:

$9t + $12c = $30

Dividing by 3, we get:

3t + 4c = 10

To find the possible pairs that satisfy this equation, we can list out the combinations:

(0, 2.5)
(1, 1.25)
(2, 0)

Now let's convert the pairs to pounds of taffy and chocolate:

(0, 2.5) - Maya can buy 0 pounds of taffy and 2.5 pounds of chocolate
(1, 1.25) - Maya can buy 1 pound of taffy and 1.25 pounds of chocolate
(2, 0) - Maya can buy 2 pounds of taffy and 0 pounds of chocolate

Therefore, the pairs that represent possible amounts of taffy and chocolate that Maya could buy are (0, 2.5), (1, 1.25), and (2, 0).
