You can divide 1000 by 4 then multiply a number to get 2500
1000/4= 250
250 x 10 = 2500
Answer: 10 hours
About 57 red pens were sold
<h3>Ratios and proportion</h3>
According to the information given:
number of packs of black pens sold: number of packs of red pens sold: number of packs of green pens sold = 7:3:4
- Total ratio = 7 + 3 + 4 = 14
- Total pen sold = 268
Number of red pens sold = 3/14 * 268
Number of red pens sold = 57 pens
Hence about 57 red pens were sold

Answer:
The man sold 190 tie-dyed T-shirts
Step-by-step explanation:
This problem can be modeled by a system of equations.
I am going to call x the number of tie-dyed T-shirts that the man sold and y the number of silk-screened shirts that he sold.
We have that he sold 5 times as many tie-dyed T-shirts as silk-screened shirts. So this gives us our equation 1)
1) x = 5y.
We also know that altogether, he sold 228 shirts. So this gives us our equation 2)
2) x + y = 228.
Now, we solve the system formed by equations 1) and 2)
x = 5y
x + 5y = 228
6y = 228
y = 38
x = 5*38
x = 190
So, in all, the man sold 190 tie-dyed T-shirts and 38 silk-screened T-shirts.
Answer: Yes that's correct
Work Shown:
(-1)^2-(-2-(9-1))
1-(-2-(8))
1-(-2-8)
1-(-10)
1 + 10
11
Note that (-1)^2 = (-1)*(-1) = 1, and subtracting a negative turns into a positive.
