Question

NEED HELP PLEASE!!!!!!!!!!!!

Answer 1

Simplify the expression

• b=85+w(10+8)
• b=85+18w

Put b=150

• 85+18w=150
• 18w=150-85
• 18w=65
• w=65/18
• w=3.6
• w=4 weeks (approx)

Answer 2

Answer: The exact answer is 3.61 weeks, so the "about" answer is 4 weeks.

Explanation:

b = $85 + w (10+8)

b = 85 + w (18)

b = 85 + 18w

b is the total amount need in the bank account, so $150.

$150 = $85 + 18w

$150 - $85 = $85 - $85 + 18w

$65 = 18w

$65 / 18 = 18w / 18

3.611 weeks = w

So, it will take about 4 weeks to get $150 in his bank account.

Hope this helps!
