Answer:
her profit is $25
Step-by-step explanation:
Given that
She spends $15 for purchasing fabric so that she make the baby blankets
And, she can make 4 blankets from one piece of fabric
Now she sold the blankets for 10 each
So we need to find out the profit
As we know that
Profit = Selling cost - purchasing cost
= (4 × $10) - $15
= 40 - $$5
= $25
hence, her profit is $25
Answer:
D = 120, there are 2 real roots for F(x)
Step-by-step explanatU
using the
formula D = b^2 - 4ac for discriminant
D = 8^2 - 4*(-7)*2
D = 64 + 56 = 120
Answer:
89/35 = 2 and 19/35
Step-by-step explanation:
In the given question, we come to know that Sammy sold 5 bottles for every 3 water bottles sold by David. In this case we get the ratio as 5:3
Now this ratio indicates that the total number of bottles can be divided into 8 parts for finding out a single part. the total number of water bottles that are sold by Sammy and David together are 160.
Now on dividing this total number of bottles by 8 we get the 20 as one part.
The,
Number of Bottles sold by Sammy = 5 * 20
= 100
Number of bottles sold by David = 3 * 20
= 60
So Sammy sold 100 water bottles and David sold 60 water bottles from the total of 160 water bottles.
