Plz , asap! a hotel offers two activity pages. one costs $192 and includes 3 hours of horseback riding and 2 hours of paasailing. the second costs $213 and includes 2 hours of horsebac riding and 3 hours of parasailing. what is the cost for 1 hour of each activity? a. parasailing: $39; horseback riding: $48 b. parasailing: $51; horseback riding: $30 c. parasailing: $27; horseback riding: $46 d. parasailing: $63; horseback riding: $24

Horseback riding costs $30 and parasailing costs $51, so B.

Step-by-step explanation:

This is answered by using simultaneous equations, let x be parasailing and y be horseback riding.

3y + 2x = 192

2y + 3x = 213

Multiply each equation by the number in front of the y of the other equation:

2 x (3y + 2x = 192)

3 x (2y + 3x = 213)

Which results in:

6y + 4x = 384

6y + 9x = 639

Simply minus the two equations to get rid of the y:

6y - 6y = 0

4x - 9x = -5x

384 - 639 = -255

The negatives cancel out which give a result:

5x = 255

x =

x = 51

So parasailing costs $51

Now you can simply plug this value into one of the equations:

3y + (2 x 51) = 192

192 - 102 = 3y

90 = 3y

y =

y = 30

So horseback riding costs $30!

Hope this helps.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

there is no answer sorry!
