The equations to determine the price in dollars for each large candle, x, and small candle, y are x+8y=68 and 3x+4y=64.

Detailed explanation:

In this scenario, a customer bought 3 large candles and 4 small candles for a total of $64. Another customer paid $4 more for 1 large candle and 8 small candles at the same store. The prices of large and small candles remain constant. To identify the equations for determining the price in dollars of each large candle (x) and small candle (y), we can see the following:

Let the price of each large candle be x and each small candle be y. Thus,

A customer at a shop paid $64 for 3 large candles and 4 small candles

This results in the equation:

⇒ 3x+4y=64.....(1)

The second customer at the store paid $4 more than the previous customer for 1 large candle and 8 small candles.

This gives us the equation:

⇒ x+8y=68.......(2)

3(2)-(1) i.e.

⇒ 3(x+8y)-(3x+4y)=68(3)-64

⇒ 20y=140

⇒ y=7

Therefore, the equations to calculate the price in dollars for each large candle, x, and small candle, y are x+8y=68 and 3x+4y=64.

Answer:

The solution to the equation is 40

This indicates the max number of wedding invitations they can afford to send within their budget.

Step-by-step explanation:

To find the zero of the function, we set the dependent variable (here, m) to zero.

So we have;

0 = 50-1.25w

1.25w = 50

w = 50/1.25

w = 40

What implication does this have in this context?

Essentially, it means that the couple can send out invitations to a total of 40 people based on their budget.
