Question

Bethany sells roses and petunias. The expression 3r+2.5p gives the cost (in dollars) of roses(r) and petunias(p). What is the cost of 2 roses and 4 petunias?

Answer 1

Answer:

Total cost = 16

Step-by-step explanation:

In the equation of cost, we can see that each rose costs 3 and each petunia costs 2.5.

To find the total cost of two roses and four petunias, we can use the values r = 2 and p = 4 in the equation given, so:

Total cost = 3r + 2.5p = 3*2 + 2.5*4 = 6 + 10 = 16

So the total cost of two roses and four petunias is 16.
