12) A new amusement park decides to offer its visitors a choice between two plans. With Plan 1 they pay $6 to enter the park and they pay $3.50 for each ride. With Plan 2 they pay $12 to enter the park and $1.50 for each ride. Write an
equation then find the number of rides when the cost will be the same. What will that cost be?

9514 1404 393

Step-by-step explanation:

The plan 1 cost for x rides will be ...

  y = 6 + 3.50x

The plan 2 cost for x rides will be ...

  y = 12 + 1.50x

These costs will be equal when ...

  y = y

  6 + 3.50x = 12 + 1.50x . . . . . substitute for y

  2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x

  x = 3 . . . . . . . . . . . . . . . divide by 2

For 3 rides, the cost will be the same.

__

For 3 rides the cost is ...

  y = 6 + 3.50(3) = 6 + 10.50 = 16.50

The cost for 3 rides will be $16.50 for either plan.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
