We know that there are 21 buttons total. x is the number of small buttons and y is the number of large buttons.
Therefore, our first equation should be x+y = 21.
We know the small buttons sell for 3 dollars, meaning 3x represents how much is made from the small buttons. The larger buttons sell for 4 dollars, meaning 4y is how much is made from the large buttons.
We also know that the total of the buttons sold is 68 dollars. Therefore 3x + 4y = 68 is our second equation.
From this information, the answer is the first set.
Answer:
Step-by-step explanation:
If 75 percent is 180 pages, we need to find the amount of pages the remaining 25 percent of the book has and add that to 180 pages because 75+25 = 100. 75/3 is equal to 25.
75:180 =
25:60.
By dividing the ratio, we found out that if Logan read 25 percent of his book, he would have read 60 pages.
180 + 60 = 240.
The total number of pages is 240
