In order to play in chess tournaments at the Marshall Club, Malik pays a fee to become a member. In addition, he pays a set rate for each tournament in which he competes. After competing in 4 tournaments Malik has paid a total of $85, and after competing in 7 tournaments he has paid a total of $130. Malik's friend Masai gets a discount on membership to the Marshall Club and pays $10 less for the membership fee than Malik. Which linear equation gives the total price, p, Masai will pay to compete in t tournaments at the Marshall Club?

p = 22.50 + 15t

Step-by-step explanation:

For Malik :

Membership fee = m

Rate per tournament = t

After 4 tournaments :

m + 4t = 85 - - - (1)

After 7 tournaments :

m + 7t = 130 - - - (2)

Subtract 2 from 1

4t - 7t = 85 - 130

-3t = - 45

t = 45 / 3

t = 15

Put, t = 15 in (1)

m + 4(15) = 85

m + 60 = 85

m = 85 - 60

m = 25

Massai pays 10% less membership fee than Malik

Hence, Massai's membership fee:

(100 - 10)% * 25

0.9 * 25 = $22.50

Total price, p, Massai will pay to compete in t tournaments ;

Total price = membership fee + (rate per tournament * number of tournaments)

p = 22.50 + 15t

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
