Step 1: Calculate the total cost of producing pPhones.
Total cost = $300000 + $150 x number of pPhones
Step 2: When we express this as an equation, we get:
$150x + 300000=250x
Step 3: Subtract 250x from both sides of the equation.
150x = 300000 - 250x
Step 4: Subtract 150x from both sides of the equation.
250x = 300000 - 150x
Step 5: Divide both sides of the equation by 100.
x = 3000
Step 6: Therefore, the Pear company should produce and sell 3000 pPhones in order to break even.
