Here are some letters and what they represent. All costs are in dollars. m represents the cost of a main dish. n represents the number of side dishes. s represents the cost of a side dish. t represents the total cost of a meal. Discuss with a partner: What does each equation mean in this situation? a. M = 7.50

The given question is incomplete

Here are some letters and what they represent. All costs are in dollars.

m represents the cost of a main dish.

n represents the number of side dishes.

s represents the cost of a side dish.

t represents the total cost of a meal.

Discuss with a partner: What does each equation mean in this situation? a. a.  m = 7.50

b. m = s + 4.50

c . ns = 6

d. m + ns = t

2. Write a new equation that could be true in this situation.

t = 3m -n(s+1)

Step-by-step explanation:

Using the information we can describe the value of each letters

using a and b

        7.50 = s + 4.50

         s = 3

substitute s in c, we get

using equation d we have

so we an equation using the above data

t +ns = 3m - n

t = 3m -n(s+1)
