Question

In a box of decorative buttons, each set of 10 buttons contains two red, three green, one yellow, and four blue buttons. How many total buttons are in a box if there are 18 red buttons?

a) 50
b) 60
c) 70
d) 80

Answer 1

The total number of buttons in the box is 90. The correct answer is not mentioned.

Step-by-step explanation:

To find the total number of buttons in the box, we need to determine the number of sets of 10 buttons. Each set contains 2 red buttons, 3 green buttons, 1 yellow button, and 4 blue buttons. If there are 18 red buttons, we can calculate the number of sets as follows:

Number of sets = Number of red buttons / Number of red buttons in each set

Number of sets = 18 / 2 = 9 sets

To find the total number of buttons, we multiply the number of sets by the number of buttons in each set:

Total number of buttons = Number of sets x Number of buttons in each set

Total number of buttons = 9 sets x 10 buttons = 90 buttons

Therefore, the total number of buttons in the box is 90. Hence the correct answer is not present in the option.
