The total number of mattresses that are sold in a year = 1,330
Percentage of King size mattresses sold = 30% = 30/100 = 0.3
Next, we have to calculate the actual number sold by using the formula given below:
Number of king size mattresses sold = Total mattresses sold in a year * percentage of king size mattresses sold
Number of King Size mattresses sold = 1,330*0.3 = 399
Number of king size mattresses sold = 399
Answer: 399
Step-by-step explanation:
Given : A mattress store sold 1,330 mattresses in one year.
If 30% of the mattresses sold were king size mattresses , then the number of king size mattresses would be
30% of 1330
Replace 'of' be Multiply sign '×' and convert percent into decimal by divide it by 100 , we get
[tex]\dfrac{30}{100}\times1330=\dfrac{39900}{100}=399[/tex]
Therefore , the number of king size mattresses were sold = 399
