Question

Somebody please help me!
This is my question.

Evaluate 12.3p + 11.7r when p = 6 and r = 7.

And then it’s written like this.

12.3(_)+11.7(_)=_+81.9
=_

Answer 1

Method:

First place the replace of p and r using brackets.

= 3(6) + 11.7(7)

3 times 6 is 18 and 11.7 times 7 is 81.9

= 18 + 81.9

add one and one together you get

= 99.9

hope it helps
