Question

Given that P = 10x+2y
Find P when:
x = 5 and y = 7
P = ?????

Answer 1

P = 64

Explanation:

P = 10 (5) + 2 (7)

P = 50 + 14

P = 64

We can also factor x + y then solve

P= 2(5x+y)

P = 2(5x5 + 7)

P = 2(25 +7)

P = 2 (32)

P = 64

Answer 2

`P=64`

Explanation:

`P=10\left(5\right)+2\left(7\right)`

`P=10\cdot \:5+2\cdot \:7`

`P=50+2\cdot \:7`

`P=50+14`

`P=64`
