Answer 1

Answer;

No of spaghetti he purchase $y=100$

Explanation:

Given,

Price of iced tea is$=\ 2$ per bottle

Price of spaghetti is $=\ 8$ per serving

Let no iced tea is $=x$

Let no of spaghetti =$=y$

$x+y=200$  

multiply by 2

$2x+2y=400$               (i)

$2x+8y=1000$              (ii)

    (ii)-(i)  

$2x+8y-2x-2y=1000-400$

$6y=600$

$y=100$

$x+y=200$

$x=200-100$

$x=100$

No of spaghetti is 100

No of iced tea is 100
