Glenn Andrews recently bought a motorcycle for $3,950. If he had to pay 6% sales tax on the bike, what was the total cost of the
wolverine [178]
The answer is C) $4,187

First you need to turn the 6% into a decimal 6%--> .06

Now you need to multiply .06 to $3,850
$3,850x.06= $237 <---Sales Tax

Now just add thesales tax to the orignal price
$3,850+$237= $4,187

Vaselesa [24]

Using a system of equations, it is found that Debbie worked 45 hours during the week.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount of hours worked by Juan.
  • Variable y: Amount of hours worked by Debbie.

Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:

9x + 9y = 765

Simplifying the expression by 9:

x + y = 85 -> x = 85 - y.

Debbie worked five hours more than juan during the week, hence:

y = x + 5.

Since x = 85 - y, we replace in the expression:

y = 85 - y + 5.

2y = 90.

y = 45.

Debbie worked 45 hours during the week.
