Let x = Horseback riding and y = Parasailing
Eq. 1
3x + 2y = 192
Eq. 2
2x + 3y = 213
By elimination:
<span> 2(3x +
2y = 192)</span>
+ -3(2x + 3y =
213)
<span> -5y = - 255</span>
y = $ 51
Substitute y :
3x + 2y = 192
3x + 2(51) = 192
<span>x = $ 30
</span>
<span>Hope this
answer will be a good help for you.</span>
132 problems because...
there are six 30 minutes in 3 hours so you would multiply 22 with 6 to get 132
(22*6=132)
