Maria : 26.50 - 0.25(26.50) = 26.50 - 6.625 = 19.88
19.87 + 0.10(19.87) = 19.87 + 1.99 = 21.86
Edwin : 0.75(26.50) = 19.88
1.10(19.88) = 21.86
and if they each have $ 23, then yes, they both ave enough money to buy the book. They both were correct in their calculations. Because taking 25% off, is the same as paying 75%.....and taking the discount price and subtracting 10% from that, is the same as multiplying by 110%. So they basically worked the same problem, just in a little different way...and they both ended up with the same answer
Hello,

and y the ordinate then
the product is x*y
Answer A
Let C(x) be the function which calculates the total cost of making x skirts.
There is going to be a fixed constant, 250, to which we will add 15$ per x skirts.
So C(x)=250+15x
Answer: 250+15x
Equation for Liz:
L = 8n
Equation for Andy:
A = 8n + 35
Step-by-step explanation:
Let the no. of necklace be 'n'
Cost per necklace= $8
Equation for Liz:
L = 8n
Because Liz sells only necklace for $8 each
Equation for Andy:
A = 8n + 35
Because Andy sells each necklace for $8 and she sold the bracelets for $35
