each kilogram of strawberries costs $ 7.5

Step-by-step explanation:

To know how much each kilogram costs, we first have to express the whole problem as an equation.

x will be the price of the ticket and y will be the price of 1 kg

1 X + 2.5 (y) = 24.75

As we know that the price of 1 ticket is $ 6 we replace that value and we can calculate the value of y.

x = 6

1(6) + 2.5(y) = 24.75

6 + 2.5y = 24.75

2.5y = 24.75 - 6

2.5y = 18.75

y = 18.75 / 2.5

y = 7.5
