Sindrei [870]

Answer:

143.70 = 3(39.95) + x

where x is the additional fee spent to race the cars at the park

Step-by-step explanation:

Let’s write the complete question first before we solve;

Blake and two of her friends are going to an amusement park. The cost of admission to the park is $39.95 per person. Once they are in the park, Blake and her friends ride the race cars, which require an additional fee. The total amount spent by all three boys is $143.70. Write an equation that can be used to find the additional fee to ride the race cars.

solution;

we are trying to write an equation that could help determine the additional fee used to race cars at an amusement park by a group of friends.

we proceed as follows;

We identify that they are 3, with each spending an amount equal to $39.95 for admission.

now to find the additional fee, we simply multiply the admission fee by 3 and subtract from the total amount spent.

let’s say the additional fee is x

This means;

143.70 = 3(39.95) + x

To get x, we can then open the bracket then take the value to the other side to get x
