    A necklace chain costs $15. Beads cost $2.50 each. You spend a total of $30 on a necklace and beads before tax. How many beads did you buy in addition to the necklace?

    Let the number of beads be b. We're given the following equation:
    2.5b + 15 = 30

    To solve for b, we type this equation into our search engine and we get:
    b = 6
