Question

A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $4.25 per pound of pecans. Over the entire day, 115 pounds of the nut mixture were sold for $358.75. If p is the number peanuts and n is the number of pecans, then the system of equations that models this scenario is:

p+n=115
p+4.25n=358.75

Determine the correct description and amount of pounds for peanuts and pecans that were sold. PLS Help

Answer 1

since p = 115-n, use that to get
115-n + 4.25n = 358.75
now find n, then p

Answer 2

HUH???

Answer 3

oh, please.
115-n + 4.25n = 358.75
3.25n = 243.75
n = 75
so p = 115-75 = 40

you need to review solving systems of equations, yeah?
