3 bottles of soda and 10 bottles of juice were purchased.

Step-by-step explanation:

Given,

Sugar in each soda bottle = 25 grams

Sugar in each bottle of juice = 40 grams

Number of bottles purchased = 13

Sugar in 13 bottles = 475 grams

Let,

x be the number of soda bottles purchased

y be the number of juice bottles purchased

According to given statement;

x+y=13     Eqn 1

25x+40y=475    Eqn 2

Multiplying Eqn 1 by 25

[tex]25(x+y=13)\\25x+25y=325\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](25x+40y)-(25x+25y)=475-325\\25x+40y-25x-25y=150\\15y=150[/tex]

Dividing both sides by 15

[tex]\frac{15y}{15}=\frac{150}{15}\\y=10[/tex]

Putting y=10 in Eqn 1

[tex]x+10=13\\x=13-10\\x=3[/tex]

3 bottles of soda and 10 bottles of juice were purchased.
