Question

95. A doll manufacturer makes happy dolls and
grumpy dolls. Each day, the number of grumpy
dolls made is two-thirds the number of happy dolls
made. If the total daily production is between 75
and 100, what is the least number of happy dolls
made? What is the maximum number of grumpy
dolls made?

Answer 1

Answer: 45, 40

If you make 45 H. dolls, you make 2/3rds * 45 G. dolls, which is 30 G. dolls. 45+30 =75, the least number you can make.

If you make 60 H. Dolls you will make 40 G. Dolls, for a total of 100 dolls, so 40 is the maximum number of G dolls you can make
