Question

1) Chynna has one hour and 20 minutes to bake muffins for the PTA bake sale. The muffins take 30 minutes to

bake fully. Each pan holds one dozen muffins. The oven holds 2 pans at once. The oven takes 10 minutes to
preheat, during which Chynna makes a large amount of batter. Write an equation can be used to find p, the number
of muffins that Chynna has time to make?

Answer 1

(80-10)/(2*2*12)

Explanation:

80 - 10 = # of minutes

= 70 minutes

In 70 minutes, you can make 2 batches.

In 2 batches, you can make 4 dozen muffins.

4 dozen = 4 x 12 = 48

Therefore the answer is 48 muffins

Equation: (80-10)/(2*2*12)
