Can you check these please?
4. A local bakery sold 60 loaves of bread in one day. If 65% of these were sold in the afternoon, how many loaves were sold in the afternoon?
Ans: x = .65 * 60
x = 39 loaves
7. Ruben bought 6new books for his collection. This increased his collection by 12%. How many books did he have before his purchases?
Ans: 6 = .12 * x
6 = .12x
6/.12 = .12x/.12
50 books = x
8. A store sold 550 video games during the month of December. If this made up 12.5% of its yearly video game sales, about how many video games di the store sell all year?
Ans: 550 = 12.5 * x
550 = 0.125x
550/0.125 = 0.125x/0.125
4400 video games = x
You're welcome.
I agree with all of your answers.
ok, thanks for checking!
true dat
To check these calculations, I will walk through the steps with you:
4. The problem states that 65% of the 60 loaves were sold in the afternoon. To find out how many loaves were sold in the afternoon, you can multiply the total number of loaves (60) by the percentage (0.65):
x = 0.65 * 60
x = 39
So, 39 loaves were sold in the afternoon.
7. Ruben bought 6 new books, which increased his collection by 12%. To find out how many books Ruben had before his purchases, we can set up an equation where 6 is equal to 12% of x:
6 = 0.12 * x
To solve for x, we can divide both sides of the equation by 0.12:
6 / 0.12 = x
50 books = x
So, Ruben had 50 books before his purchases.
8. The store sold 550 video games in December, which made up 12.5% of its yearly video game sales. To estimate the total number of video games sold in a year, we can set up an equation where 550 is equal to 12.5% of x:
550 = 0.125 * x
To solve for x, we can divide both sides of the equation by 0.125:
550 / 0.125 = x
4400 video games = x
So, the store sold approximately 4400 video games in a year.
