Work Step by Step
Estimate the cost to purchase 17 laptops by rounding the cost per laptop, rounding the number of laptops then multiplying the two numbers.
506≈500
$17 \approx 20$
500×20=10,000
Estimate the cost to purchase 13 printers by rounding the cost per printer, rounding the number needed, then multiplying the two numbers.
482≈500
13≈10
500×10=5,000
Find the total approximate cost by adding together the approximate cost for laptops and the approximate cost for printers.
10,000 + 5,000 = 15,000
Find the exact cost to purchase 17 laptops by multiplying the cost per laptop by 17.
506×17=8,602
Find the exact cost to purchase 13 printers by multiplying the cost per printer by 13
482×13=6,266
Find the total cost by adding together the cost for laptops and the cost for printers.
8,602 + 6,266 = 14,868
