Hello Everyone,
Today I just cracked open my Translation Book from MGMT- going through all of them until the test.
On pg 13 there is a question that has one confusing part, please explain if you can:
A candy company offers premium choclates at $5 per pound. They also offer regular chocolates at $4 per pound. If Barrett buys Michelle a 7-pound box of Valentines choclates that cost him $31, how many pounds of premium choclates are in the box?
Now I get this part:
Let p= the number of pounds of premium chocolate
Now why does: 7-p= the number of pounds of regular chocolate? I am not sure how they got the minus?
This is the equation they produced:
31 = 5p + 4(7-p)
Appreciate your help

This is right. You have two equations here.
Set P = Number of pound of Premium
R=Number of pound of Regular
Equation 1, price:
5P+4R = 31
Equation 2, weight:
P+R = 7
=> R = P-7
Plug in eq 1 with the eq 2 obtained:
5P + 4(P-7) = 31
