Question

Janet is shopping for silver as an investment. At her local silver shop she is presented with two options: round coins and rectangular bars. She looks at the

prices for each.
●
The silver shop will sell her round silver coins according to the equation p=
27s which shows the relationship between s, the number of ounces of silver
she buys, and p. what she will pay for the round coins.
The silver shop will sell her rectangular silver bars but they are more popular
so she has to pay a premium to acquire the rectangular bars. The equation p
= 27.5s +50 shows the relationship between s, the number of ounces of
silver she buys, and p, what she will pay for the rectangular bars.
Janet intends to buy 40 ounces of silver at the silver shop. How much money will
she save by purchasing only round coins instead of rectangular bars?​

Answer 1

To determine how much money Janet will save by purchasing round coins instead of rectangular bars, we need to find the difference in cost between the two options.

First, we can find the cost of the round coins by plugging 40 ounces into the equation p=27s:

p = 27 * 40 = 1080

Next, we can find the cost of the rectangular bars by plugging 40 ounces into the equation p = 27.5s + 50:

p = 27.5 * 40 + 50 = 1100

The difference in cost between the two options is 1100 - 1080 = $<<1100-1080=20>>20. Therefore, Janet will save $20 by purchasing round coins instead of rectangular bars.
