B, C, E
Step-by-step explanation:
Answer choice A):
$300 × = $75
* This answer choice represents the calculation of discount only and not the final selling price of the bicycle.
Answer choice B):
$300 × = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
Answer choice C)
$300 × (1 - ) = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
Answer choice D):
$300 - 1/4
*This answer choice shows an incorrect equation which neither represents the calculation of the discount nor the final selling price of the bicycle.
Answer choice E):
$300 - × $300
Applying the rule of PEMDAS,
We start with division; 1 ÷ 4 = 0.25
Then we go to multiplication; 0.25 × $300 = $75
Finally we do the subtraction; $300 - $75 = $225
* This answer choice represents the calculation of the final selling price of the bicycle.
