Simple....

you have 7(5x+3)+3(12-x)....

just take them apart....

7(5x+3)

distribute the 7...

7*5x=35x
and
7*3=21

Now, the other part...

3(12-x)

Distribute the 3...

3*12=36
and
3*-x=-3x   

Now, add what you have found....

35x+21+36-3x

32x+57

Thus, your answer, A.

Alinara [238K]

Answer:

Step-by-step explanation:

Step 1:

x - > number of Avocado

y -> number of melon

Step 2:

x ≤ 3y

x +  y ≥ 20

Step 3:

x + y≥ 20

     y ≥ -x + 20

Step 4:

( 1 , 20)

x ≤ 3y               ; y≥ -x + 20

1 ≤ 3*20          ;  20 ≥ -1 + 20

1 ≤ 60              ; 20 ≥ 19
