17x + 16x + 12x =180
45x = 180
x = 4

Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:

1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:


Using this value of x in first equation, we get:

Thus the cost of one hot dog is $1.20
Take out the GCF of 75 and 12 which is 3:-
= 3(25t^2 + 4)
That's it
