The manager could perform scalar multiplication on Matrix A, using the scalar 1.15.

Option C is correct

Reason :

Increasing the price by 15% would mean we are taking 100% of the value + another 15%; 100+15 = 115%; 115% = 115/100 = 1.15.

Hence ,Multiplying every value in Matrix A by 1.15 will give the price raised by 15%.

solong [7]
Exercising doesn't mean you have to spend hours in the gym. Exercises can be done at the comforts of your home too, and there's plenty of exercise available, especially for those who have less time to do so. Just like for example, waiting time. While you are waiting for your clothes in the washing machine to finish, you may use this time to do some basic exercises such as running in place, jumping jacks or carrying weights.

katrin2010 [14]
The standard quantity that is produces is multiplied to the standard price. The product is subtracted to the quantity variance and will be divided to the standard price. The product you have acquired will be the units that are produced.

4,500 pounds x $2.50 = 11,250
11,250 - $375  = 10,875
10,875 / $2.50 = 4,350

Answer: There are 4,350 units produced.
