Answer:

Step-by-step explanation:

Step 1: Obtain zero on one side and then factor. Step 2: Set each factor equal to zero. Step 3: Solve each of the resulting equations. This technique requires the zero factor property to work so make sure the quadratic is set equal to zero before factoring in step 1.

If were you, i will use trial and error to make it easier :)) [if the number is small,you can use trial and error, but if a big number use quadratic eq. Or divide the big num. to get smaller num.]

C seems to make the most sense, logarithmic and exponential functions are not gradual, and a step function just wouldn't fit in my eyes.

Answer 1: y = 35x + 50

Answer 2: will

Answer 3: $10

Step-by-step explanation:

Equation: y = 35x + 50

Registration fee is one time, so you just add to it.

You have to pay each time you go to a session, so x will be the amount of sessions, 35 will be the price of each session.

You can plug in the 8 to the equation, then solve for y:

y = 35(8) + 50\\y = 280 + 50\\y = 330

They will be able to pay for it because: 330 < 340

They will have $10 left because:

340 - 330 = 10

340 is how much on the card and 330 is how much the 8 lessons (in total) cost.
