Oliva has signed up for snowboarding lessons. Her parents set a limit of 400$ for costs for the season. It costs 250$ to get a mountain pass plus 9.5$ for each practice session. What is the maximum number of practice sessions that Olivia can go to?

15

Step-by-step explanation:

(400-250) divided by 9.5

15

Step-by-step explanation:

So, to solve this I made this is 400> or equal to 250+9.5x. X being the number of times she goes to the practices.

400> or equal to 250+9.5x

-250                    -250

150 > or equal to 9.5x

/9.5                       /9.5

15.789> or equal to x

If you then simplify that, you get 15 because you can't necissarily take .789 of a lesson.

Hope this helps!

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
