x*(1.035) + (4,200-x)*(1.045) = 4,374.00
1.035x + 4,389.00 -1.045x = 4,374.00
15.00 = .01x
x = 1,500 so x (1,500) invested at 3.5% and
(4,200 - 1,500) (or 2,700) invested at 4.5%

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
