For every 30 puffs that Adam bakes,
he bakes 20 cookies.
He bakes a total of 100 puffs and cookies.
- How many cookies does he bake?
- How many more puffs than cookies does he bake?
(a)
Number of puffs and cookies per set
= 30 + 20
= 50
Number of sets
= 100 ÷ 50
= 2
Number of cookies that Adam bakes
= 2 x 20
= 40
(b) Number of puffs that Adam bakes
= 2 x 30
= 60
Number of more puffs than cookies
= 60 - 40
= 20
Answer(s): (a) 40; (b) 20
