Answer 1

Answer:

A) 1.18b

Step-by-step explanation:

Hailey writes the expression $b+0.18b$ to compute her bill with a tip, where b is her bill before the tip.

Use dictributive property:

$a\cdot (b+c)=a\cdot b+a\cdot c$

In the expression $b+0.18b,$ we can write b before brackets:

$b+0.18b=b(1+0.18)=1.18b$
