Question

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

Answer 1

Answer:

$P=64$

Step-by-step explanation:

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

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

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

$P=50+14$

$P=64$

Answer 2

Answer:

P = 64

Step-by-step 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
