The answer is C) 228

How?

b + m = 342

b = 2m

2m + m = 342

3m = 342

m = 114

<em>Substitute to the original equation, "b + m = 342".</em>

b + 114 = 342

b = 228

Answer:

$204.11

Step-by-step explanation:

To find 70% of $269.99, multiply $269.99 x .7 = $188.99.

To find the 8% sales tax on $188.99, multiply $188.99 x .08 = $15.12.

Add the $15.12 of sales tax onto the cost of $188.99 = $204.11
