Mr. Garza's family is attending the local soccer game. He has 30 to spend on food and drinks . The cost of chips is $2 and the c
ost of a drink is $3 . Which of the following inequalities represents all possible combinations of c , and d, the number of drinks , that Mr. Garza can purchase?
let x and y be the number of chip and pretzel bags respectively :
4x%2B2y%3 C=20
:
if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8 :
if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4 :
so chips 1 and pretzels 8 :
chips 3 and pretzels 4.
F(2) is referring to the 2 on the x-axis. You can see that the point aligning with 2 on the x-axis is also 2 on the y-axis. Therefore, f(2)=2! hope that helped
