$We first name an unknown to represent the store's cost for the computer.$	$C = store’s cost for the computer$	Theory & Tactics Method Card TRANS1-A Click to view full details
$We translate "selling price of 2,240USD" minus the cost equals "profit of 40 percent of the store's cost" .$	$2240 - C = \frac{40}{100} \times C$	Theory & Tactics Method Card TRANS1-B Click to view full details Theory & Tactics Method Card TRANS2-A Click to view full details Theory & Tactics Method Card TRANS3-A Click to view full details
$We isolate the cost by combining like terms.$	$2240 = \frac{140}{100} \times C$	Theory & Tactics Method Card EQUA1-A Click to view full details
$We solve for the store's cost by dividing both sides by 140 and multiplying by 100.$	$C = \frac{2240 \times 100}{140} = \frac{2100 \times 100}{140} + \frac{140 \times 100}{140}$	Theory & Tactics Method Card EQUA1-A Click to view full details
$We simplify the fractions by cancelling out terms$	$C = \frac{140 \times 15 \times 100}{140} + \frac{140 \times 100}{140} = 1500 + 100 = 1600$	Theory & Tactics Method Card EQUA1-A Click to view full details
$We translate "profit of 50 percent of the computer's cost" into the new selling price formula.$	$New SP = C + \frac{50}{100} \times C = 1.5 \times C$	Theory & Tactics Method Card TRANS2-D Click to view full details
$We substitute the cost into the formula to find the new selling price.$	$New SP = 1.5 \times 1600 = 2400$
