Where Q represents the weekly quantity produced and sold in thousands of units.
Last week 150,000 units were produced and soldWhat was the total cost last week ?
A. $420550
B. $550420
C. $592000
D. $970000For this question I’ve got 420550 as answer but the answer is actually D. $970000
How is it so?You have not read the question carefully enough.
The question says that Q is the quantity in thousands of units.
Therefore Q is 150 (not 150,000) in the equation.
550 + 2.8 x 150 = 970 and the question says that this is the total cost in $000, so is 970,000.
