We are given
selling price of one flower is $0.50
so, 
Let's assume
she sold 'n' flowers to get $20
so, total amount she get after selling 'n' flowers is


This is supposed to be $20
so, we can set it equal to 20

now, we can solve for n
we get

we are given
she makes $6.00 on every $20 worth sold
so, we can find cost of 40 flowers is 20-6
total cost is 14
or cost of 40 flowers is $14
now, we can find cost of one flower


so, cost of each flower is 35 cents...............Answer

Answer:
y = 15x + 200
Step-by-step explanation:
It should be y = 150x + 200 because if you look at the first one, 300x is too big.
You can cross out the last two.
Then you can see the second one also doesn't work.
Cross that one out.
The first choice is the only one.
Answer:
11.27
Step-by-step explanation:
So here's gives that
total weight of 25 bags = 50 x 25
= 1250
total cost of 25 bags weighing 50 kg is = 15000
cost of 1 kg = 15000 ÷ 1250 = 12
now total weight of 15 bags weighing 30 kg = 450
cost per kg = 12
cost of 15 bags weighing 30 each = 450 x 12
Answer = 5400 rupees.
