Question

1.Angelica's service club is selling flowers for a fundraiser. Each flower costs them $0.50 to purchase. They set the sale price of each flower at the purchase price plus 40%. Write and solve an equation to determine how many flowers they will need to sell to make a profit of $500. Use complete sentences to explain what each number and variable in your equation represents. Write your solution in the context of the original problem.

Answer 1

$0.50 to purchase
sale price = .50(1.40) = $ 0.70
this means they make $ 0.20 profit per flower
0.20f = 500
f = 500/0.20
f = 2500
Angelica's service club would have to sell 2500 flowers to clear a profit of $500.
====================================
10A + 6C = 80
C = 5
now sub
10A + 6(5) = 80
10A + 30 = 80
10A = 80 - 30
10A = 50
A = 5

check..
10A + 6C = 80
10(5) + 6(5) = 80
50 + 30 = 80
80 = 80 (correct)

If there were 5 children in the group, that means there were also 5 adults.
=======================================...
| x - 0.525| = 0.01

x - 0.525 = 0.01
x = 0.01 + 0.525
x = 0.535

-| x - 0.525| = 0.01
-x + 0.525 = 0.01
-x = 0.01 - 0.525
-x = 0.515
x = - 0.515

minimum is : -0.515 diameter
maximum is : 0.535 diameter
