The equation for the total amount charged is y = 60 + 45x
<h3>How to create the equation?</h3>
The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x

Because there are 6 letters in WINNER, you can use factorials to find out how many ways the letters can be arranged.
Factorials are represented with the ! symbol. Use the factorial of 6 to solve the problem:
There are
720 different ways the letters can be arranged.
S(t) = S0·(1 + rate)t<span>S(t) = salary at year t
<span>S0 = starting salary = $35,000
</span>rate = 4% = 0.04
