Question

What is the value of 3(2p + 4R) when P = 0.8 and R = 1.5

Answer 1

remove parentheses = 3(2*0.8+4*1.5), then Multiply numbers= (3(4*1.5+1.6), then Multiply again= 3(6+1.6), and add the numbers=3*7.6
The answer will be 22.8

Answer 2

3(2p + 4R) when P = 0.8 and R = 1.5
= 3(2*0.8 + 4*1.5)
= 3(1.6 + 6)
= 3(7.6)
= 22.8
