Afina-wow [57]

Answer:

Instrumental understanding – having a mathematical rule and being able to apply and manipulate it. Relational understanding – having a mathematical rule, knowing how to use it AND knowing why it works.

Step-by-step explanation:

Instrumental understanding involves “memorising which problems a method works for and which not, and also learning a different method for each new class of problems” (Skemp 1987, p. 159), is a desire to know “some kind of rule for getting the answer” (p. 155) so that a student can “latch on it and ignore the rest”

the initial price of a home entertainment system is $34,000. It is discounted by 10% and then by a further 26%. Find the price o
maria [59]
The final price of the item is $22,644

The initial discount of 10% leaves the price at 90% of the retail value:
\frac{x}{34000}  =  \frac{90}{100}
cross multiply to solve for x:
100x = 3,060,000
x = 30,600
This new price is then discounted 26%, which means the final price is 74% of $30,600:
\frac{x}{30600}  =  \frac{74}{100}
cross multiply to solve for x:
100x = 2,264,400
x = 22,644
The final price of the home entertainment system is $22,644

We need to mix 1.875 quarts of grape juice with 3.75 quarts of sparkling water.

We need to mix 18 quarts of sparkling water with 9 quarts of grape juice.

Let y be the amount of grape juice need to mix with 3.75 quarts of sparkling water, then

\frac{3.75}{y}=\frac{1.5}{0.75}\\\Rightarrow\ y=\frac{3.75\times0.75}{1.5}\\\Rightarrow\ y=1.875
