Let x equal the number of books:
30 ≥ 4x+2
You don’t want to spend more than $30, so you want to spend as close to $30 as possible, or equal it.
Find the cost of all the items together.
4.99 + 0.46 + 0.89 = $6.34
Find the sales tax.
6% = 0.06
6.34 * 0.06 = 0.3804
Add.
6.34 + 0.3804 = 6.7204
Round.
6.7204 = 6.72
He spent approximately $6.72
Hope This Helped! Good Luck!

y = -x/5 + 5
or
x + 5y = 25
