A hospital's medical billing and coding manager has allocated $12,000 to buy new desktop computers
and $9,000 to buy new printers.
If a desktop costs $1,000 and a printer costs $3,000, how many total pieces of equipment can the
medical billing and coding department purchase? (Enter numerical values only) - correct answer ✔15
Step 1: Determine the number of desktops by dividing the budget for the desktops by the price of a
single desktop.
$12,000 ÷ $1,000 = 12
Step 2: Determine the number of printers by dividing the budget for the printers by the price of a single
printer.
$9,000 ÷ $3,000 = 3
Step 3: Add the number of desktops and printers from Step 1 to find the total.
12 desktops + 3 printers = 15 total

1321.5 - correct answer ✔1231.5
Step 1: Set up long multiplication. Ignore the decimals for now (we deal with those later when we
multiply).
