Question

Alain has spent 40 minutes on his homework. If he is 40% done, how many minutes will he spend on his homework in total ?

Answer 1

Alain has done 40 minutes which is 40% of his work done.

Let m = minutes he must add to 40 to get a total for homework time.

m = (0.40)(40) + 40

m = 16 + 40

m = 56
