Question

Ryan's brother Joel weighs 30% more than Ryan together the boys way 276 pounds in pounds how much does Joel weigh

 

Answer 1

Let J be Joel's wight and R be Ryan's weight then

 

we form an equation using  given information 

 

J + R = 276

 

but J = R + 0.30R

 

= 1.30R

 

now substituting for j in the equation

 

2.30R = 276

 

R = 276 / 2.30

 

= 120

 

J = 276 - 120 

 

= 156 lbs 

 

 

thats your answer hope  I helped.

Answer 2

R = Ryan's Weight

J = Joel's weight

 

Joel weighs 30% more than Ryan

J = 1.3R

 

Together they weigh 276 pound

R + J = 276

 

Substitute the 1.3R for J in the second equation.

 

R + 1.3R = 276

 

Solving for R

2.3R = 276

R = 120

J = 1.3R = (1.3)(120) = 156 <-- Joel's weight.
