Ilyas has a $50 online gift voucher. He plans to buy as many books as he can with it. The cost of each book is $4. There is also a single shipping charge of $7.50. How many books can he afford without spending more than his gift voucher amount?

10

Step-by-step explanation:

Set up an inequality

4x + 7.50 50

4x   42.50

x    10.625

So the answer is 10 because you can't buy .625 of a book

y=mx+

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
