Question

Any help please? Having a hard time

Answer 1

Answer:

the answer is c

Step-by-step explanation:

x and y have to be at least 12, so that's why the greater than sign was used

the amount of money had to be at most $230, so that's why the less than sign was used

they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y

Answer 2

Answer:

x+y ≥ 12

18x+20y ≤ 230

Step-by-step explanation:

At least means that is the smallest number they can buy, so they must buy at least 12

x+y ≥ 12

no more than 230 means that is the maximum amount they can spend

18x+20y ≤ 230
