Answer:
Yes, Bill surpassed his target by £2,200.
Step-by-step explanation:
The cost for the laptops totals = 50 x 400
= 20,000
He sold 40 laptops with a profit margin of 30%
Calculating that gives (40 x 400) x 1.30
= 20,800
He sold 10 laptops with a profit of 15%
Calculating that gives (15 x 400) x 1.15
= 6900
Thus, the overall sales revenue totals
= 20800 + 6900 = 27,700
Response:
P(largest or smallest) = 0.30 + 0.20 - 0.15
Detailed explanation
You add the probabilities of choosing the largest and smallest without double counting the chance of selecting both.
Let x represent the hot dogs
and y represent the snacks
The equation x + y = 175
Rewrite x as 175 - y
And the second equation: 2.50x + 0.75y = 262.50
Substitute to get 2.50(175 - y) + 0.75y = 262.50
Which simplifies to 437.50 - 2.50y + 0.75y = 262.50
Rearranging gives -1.75y = -175
Hence, solving for y results in y = -175 / -1.75 = 100
Thus, 100 snacks and 75 hot dogs were sold
20*117.98 + 20*124.32 = $4846.00
<span>$4846.00*1.02 = $4942.92 </span>
<span>40*128.48 = $5139.20 </span>
<span>0.02*5139.20 = $102.78 </span>
<span>$5139.20 - $102.78 = $5036.42 </span>
<span>$5036.42 - $4942.92 = $93.50,
Thus, the result is (B)</span>
<span>9 ten thousandths equals 0.0009, which can be expressed as 9 × 10 to the power of -4</span>
