Answer:
5 rings
Step-by-step explanation:
Given the following :
Cost of ring = $18 per ring
Total amount held = $120
Amount spent on jeans = $30
The number of rings Benito can buy can be represented as :
The total cost of rings plus the cost of jeans should be less or equal to the total amount held.
Total cost of rings ($18 * r) + Cost of jeans ≤ Total amount held
18r + 30 ≤ 120
18r ≤ 120 - 30
18r ≤ 90
r ≤ 90/18
r ≤ 5
