(13) The Modern Grocery has cashews that sell for $5.00 a pound and peanuts that sell for $2.00 a pound. How much of each must Sam, the grocer, mix to get 120 pounds
of a mixture that he can sell for $360.

solution:

x = pounds of cashews = 20

y = pounds of peanuts = 70

Step-by-step explanation:

x = pounds of cashews

y = pounds of peanuts

---

4.75x + 2.50y = 3.00*90

x + y = 90

---

put the system of linear equations into standard form

---

4.75x + 2.50y = 270

x + y = 90

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
