Whats 2r + 1 if r = 3

answer is 7

Step-by-step explanation:

Given that r = 3

We replace r to be 3

2(3) + 1 multiply 2 by 3, then add 1

(2 x 3) + 1

= 6 + 1

= 7

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
