P varies directly with Q and inversely with R, on the contrary, P varies inversely with R, this means P and R are indirectly proportional. In simple terms it means whatever you do to P, you do the opposite to R. Or P=K*Q/R

18=k*5/2
18=5k/2 
5k=36 
k=36/5

P=K*Q/R
p=(36/5)(20/10) 
p=72/5

Adult tickets to an amusement park cost x dollars. Children's tickets cost y dollars. The Henson family bought 3 adult and 1 chi

Alex787 [66]

Henson's cost: 3x+y=203

Garcia's cost: 2x+3y=189

Step-by-step explanation:

Given,

Cost of each adult ticket = x dollars

Cost of 3 adult ticket = 3x

Cost of 2 adult ticket = 2x

Cost of each child ticket = y dollar

Cost of 3 child ticket = 3x

Henson's cost;

3 adult tickets + 1 child ticket = $203

3x+y=203

Garcia's cost;

2 adult tickets + 3 child tickets = $189

2x+3y=189

Henson's cost: 3x+y=203

Garcia's cost: 2x+3y=189
