Question

a candy dispenser put various numbers of orange candies into bags. how many bags of candy are there in all?

Explanation:

Step1: Identify the number of bags in each interval

• For \(1 - 20\): \(3\) bags
• For \(21 - 40\): \(6\) bags
• For \(41 - 60\): \(4\) bags
• For \(61 - 80\): \(1\) bag
• For \(101 - 120\): \(3\) bags
• For \(121 - 140\): \(3\) bags

Step2: Sum up the number of bags

$$3 + 6+4 + 1+3 + 3$$

$$=(3 + 6)+4 + 1+(3 + 3)$$

$$=9+4 + 1+6$$

$$=(9 + 4)+(1 + 6)$$

$$=13+7$$

$$=20$$

Answer:

\(20\)
