Answer 2

Answer:

82.3

Step-by-step explanation:

Hi there!

We are given the expression 12.1p+11.5r, and we want to evaluate it if p=3 and r=4

We need to simply substitute the given values into 12.1p and 11.5r respectively, then add the numbers together

If p is equal to 3, then that means that 12.1p is equal to 12.1*3, which would be 36.3

If r is equal to 4, then that means 11.5r is equal to 11.5*4, which would be 46

Now add 36.3 and 46 together

36.3+46=82.3

Hope this helps!
