Answer 1

Answer:

2

Step-by-step explanation:

$52 7books $6 CB which means she brought 2 which is $12$8 TB and then 7-2 because he already brought 2 CB so that means that he brought 5TB which is 40 Then add 40 +12 = $52 for 7 books 

Answer 2

cookbooks be x

travel books be y

• x+y=31--(1)
• 2x+5y=107--(2)

(1)×2

• 2x+2y=62--(3)

Subtract (3) from (1)

• 3y=45
• y=15

Now

• x=31-15
• x=16
