Bethany sells roses and petunias.The expression 3r plus 2.5p gives the cost (in dollars) of r roses and p petunias.What is the cost of 7 roses and 8 petunias
Answer:
The total cost is $41.
Step-by-step explanation:
The given expression is :
@@MATH_TOKEN_0@@
Now we know that the roses are represented by = r
And the petunias are represented by = p
So, we can say that each rose costs $3 (3r) and each petunia cost $2.5 (2.5p)
So, we can now find the total value of 7 roses and 8 petunias.
Cost of 1 rose = $3
Cost of 7 roses is = \(7\times3=21\)
Cost of 1 petunia is = $2.5
Cost of 8 petunias is = @@MATH_TOKEN_2@@
Total cost of the flowers = @@MATH_TOKEN_3@@ = $41.
