Answer:
7 items
Step-by-step explanation:
Sherry and Laura want to buy a new Ipod. Sherry has already saved $49 and will earn the rest by selling necklaces for $5 each. Laura doesn’t have any money saved, but will sell bracelets for $12 each. How many items must they sell to have the same amount saved for an Ipod?
49 + 5x = y
12x = y
7 items later
49+5(7)=84
12(7)=84
Answer:
It will take 6 days to have the same number of followers
Step-by-step explanation:
Set up the system of equations
Ms. W
y = 75x+400
Mrs Hill
y = -25x+1000
Because they both equal y we can set them equal to each other.
75x + 400 = -25x + 1000
Get x alone
75x+25x = 1000 - 400
100x = 600
Solve
x = 6
Hope this helps,
