Answer:

Equation: y=100+8x

18 Classes: $244

Step-by-step explanation:

For the equation, you know that 100 is the annual fee. this means that regardless of how many classes you take, you'll pay 100 dollars per year at least. this is where the y=100+ comes from, since it's $100 plus whatever the amount of class fees. Then, the cost of each class is 8. This means it'll be 8 dollars times the number of classes takes (represented by x). That's where you get y=100+8x.

For the second part, you'll want to plug the number of lessons into the equation. since there are 18 lessons, you substitute that for x, so you get that the total cost (y) is equal to 100+8(18). then you simplify that and get 100+144, which equals $244

Y=8x+100

y=8(18)+100
y=144+100
y=244

Sales tax in the state of Florida is 7%. Bob purchased a coat that was marked $350.00. What is the total bill including tax?

pav-90 [236]

To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50

This is the amount of tax. Now add it to the original price for the total cost.

$350.00 + $24.50 =

$374.50
