 No of Quantity ( SP - CP ) = Total Profit

140 ( s - 16 ) = 5600

So, s - 16 = 40

So, s = 56

Hence, correct answer will be (D) 56

Profit= Selling Prize - Cost Price
$5600 = (No. of units * SP per unit) - 140*16 5600 = 140* SP per unit - 140*16 5600 + 2240 = SP per unit = 7840/140 = 56 D Manager Joined: 29 Feb 2016 Posts: 116 Location: India GMAT 1: 700 Q49 V35 GPA: 3 Re: An electrical supplies store sells 140 power stabilizers every week.

A. 24 B. 26 C. 40 D. 56 E. 60 We use the profit formula: revenue - cost = profit. We can create the following inequality in which n = selling price per unit: 140n - 140 x 16 ≥ 5600 140(n - 16) ≥ 5600 n - 16 ≥ 40 n ≥ 56 Answer: D _________________ # Scott Woodbury-Stewart Founder and CEO Scott@TargetTestPrep.com 122 Reviews 5-star rated online GMAT quant self study course See why Target Test Prep is the top rated GMAT quant course on GMAT Club.

A. 24 B. 26 C. 40 D. 56 E. 60 Let $$x$$ be the selling price of each unit. So, from the passage we have - $$5600 = x * 140 - 16 * 140$$ $$x = 56$$ _________________ If my Post helps you in Gaining Knowledge, Help me with KUDOS.. !!

A. 24 B. 26 C. 40 D. 56 E. 60 Let x = the selling price per unit So, x - 16 = the PROFIT on ONE unit And 140(x - 16) = the PROFIT on the sale of 140 units (aka the weekly profit) What is the minimum selling price per unit that will ensure a weekly profit of at least$5600 from sales of power stabilizers?
In other words, we want: weekly profit ≥ 5600
Or we can write: 140(x - 16) ≥ 5600
Divide both sides by 140 to get: x - 16 ≥ 40
Add 16 to both sides to get: x ≥ 56

So, the selling price per unit must be \$56 or greater

Cheers,
Brent
