Method 1:
Method 1:
Step1: Keywords/Values and
Keywords/Value: [Unit: 4 times ipad as laptop
$value: ipad sold more by $3480, total = $8400]
Draw/Working:
Step2: Link the numbers
$i + $l + 3480 = 8400
$i + $l = 8400 - 3480
= 4920
$i = $l
$l = 4920/2 = $2460
Step3: Solve by forming equation
ipad sales = $3480 + $2460 = $5940
laptop = $2460
For u unit of ipad and laptop, the values are
ipad = 5940/4 = 1486
Value of u unit of laptop = 2460
Value of u unit of ipad = 1486
Since laptop is $325 more for each laptop,
Laptop: 1486 + 325u = 2460
325u = 2460 – 1485
= 975
u = 975 / 325
= 3
3 laptops are sold.
