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!
