Is that the real answer at the top and what’s the Raleigh Rocket’s score ?

liubo4ka [24]

Answer:

The scores are as follows:

Caroline Castways = 72

Raleigh Rockets = 24

Step-by-step explanation:

Let c be the Castways score and r be the Raleigh Rocket’s score

Then

According to given statements, the equations will be:

$c+r = 96\\r = \frac{1}{3}c$

From equation 2

$3r=c$

Putting c = 3r in equation 1

$3r+r = 96\\4r = 96\\\frac{4r}{4} = \frac{96}{4}\\r = 24$

Putting the value of r in equation 2

$r = \frac{1}{3}c\\24 = \frac{1}{3}c \\c = 24*3\\c = 72$

Hence,

The scores are as follows:

Caroline Castways = 72

Raleigh Rockets = 24
