1.70p
2p - .30
.70p
p (1 - .30)

Answer 1

.70p

p(1-.30)

Explanation:

Tony plans to purchase a jacket that costs p dollars. In a week the jacket will go on sale for 30% off.

Tony writes althea following expression

p - .30p

Here P or 1P are same

So expression becomes 1p - 0.30p

Both are like terms

so we can subtract it

1p - 0.30p = 0.70p

Also we can write 1p - 0.30p as p(1-0.30)

We can take out p that is in common

Equivalent expression is .70p and p(1-.30)
