Answer 1

a). 6 n≤60, n≤10

b). The maximum number of books you can buy=10

Explanation:

a). Step 1: Derive expression

Total cost of the books can be expressed as;

T=p×n

where;

T=total cost of book

p=cost per book

n=number of books to be bought

In our case;

T=$60

p=$60

n=n

replacing;

Since she has a limited budget of $60, the total cost of the book should not surpass $60

60≥6×n

6 n≤60

b). n=60/6=10

The maximum number of books you can buy=10
