The equation representing Total money spend being as a member is![m = 60+7.6(b-1)](/tpl/images/0422/5506/28022.png)
Step-by-step explanation:
Given:
Memberships charges = $60
Cost of 1 book = $7.60
Let number of books be 'b'.
We need to find Total money 'm' spend yearly on buying books after becoming member.
Now we know that 1 book is free for a member.
Total money spend 'm' will be equal to Sum Memberships charges and Cost of 1 book multiplied by number of books bought yearly minus 1.
Framing in equation form we get;
Hence The equation representing Total money spend being as a member is![m = 60+7.6(b-1)](/tpl/images/0422/5506/28022.png)
