Question

The flower shop sold roses and tulips. The number of roses sold was 5 less than twice the number of tulips sold. If the shop sold 106 flowers in total, how many of each kind of flowers were sold?

Answer 1

Answer: the number of roses sold is 69 while number of tulips is 37

Explanation:

Let x represent the number of roses that the flower shop sold.

Let y represent the number of tulips that the flower shop sold.

The number of roses sold was 5 less than twice the number of tulips sold. This means that

x = 2y - 5 - - -- -- - - - - - ;1

If the shop sold 106 flowers in total, it means that

x + y = 106

Substituting x = 106 - y into equation 1, it becomes

106 - y = 2y - 5

3y = 106 + 5 = 111

y = 111/3 = 37

x = 106 - y = 106 - 37

x = 69
