......

iii - i
500p = 1500
p = 3

From ii
24*3 + 14q = 100
72 + 14q = 100
14q = 28
q = 2

3 apples and 2 avocado would do.

-
Let x = number of apples
Let y = number of avocados

100x + 350y = 1000
24x + 14y = 100

100x + 350y = 1000
14y = 100 - 24x

100x + 350y = 1000
7y = 50 - 12x

100x + 350y = 1000
100x + 50( 7y ) = 1000
100x + 50( 50 - 12x ) = 1000
100x + 2500 - 600x = 1000
-500x = -1500
x = 3

100x + 350y = 1000
100( 3 ) + 350y = 1000
300 + 350y = 1000
350y = 700
y = 2

Three apples, two avocados.

ANS: 3 apples and 2 avaocado

100x + 350y = 1000 (calories)
24x + 14y = 100 (carbs)

100x + 350y = 1000 ; eq1(say) = 10x + 35y = 100
24x + 14y = 100 :eq2(say)

10x + 35y = 100 :eq1
24x + 14y = 100 :eq1

you get x = 3 and y = 2 by solving those two equations.

-
Let x represent the number of apples
Let y represent the number of avocados

Calorie total: 100x + 350y = 1000
Carb total: 24x + 14y = 100
Note: x and y must be whole numbers.

I get x = 3 and y =2
