Enrique is baking muffins and bread.
He wants to bake a total of ten batches.
Each batch of muffins bakes for 30min, and each batch of bread bakes for 50 min.
Let m represent the number of batches of muffins.
- write an expression for the total time required to bake a combination of muffins and bread if each batch is baked separately.
:
Let m = no. of batches of muffins
the total is 10 batches, therefore
(10-m) = no. of batches of bread
:
time in terms of m
:
Time = muffin time + bread time
t(m) = 30m + 50(10-m)
t(m) = 30m + 500 - 50m
t(m) = 30m - 50m + 500
t(m) = -20m + 500
