Answer:

( x = 5 ), ( y = 80 ).

Step-by-step explanation:

If ( y ) is directly proportional to ( x ), we can use the formula for direct variation:

[ y = kx ]

where ( k ) is the constant of proportionality.

Given that ( y = 24 ) when ( x = 1.5 ), we can substitute these values to find ( k ):

[ 24 = k \times 1.5 ]

Solving for ( k ):

[ k = \frac{24}{1.5} = 16 ]

Now that we know ( k = 16 ), we can use this value to find ( y ) when ( x = 5 ):

[ y = 16 \times 5 = 80 ]

Therefore, when ( x = 5 ), ( y = 80 ).
