Answer:
Sheena has saved $16
Step-by-step explanation:
To find out how much Sheena has currently saved, we need to backtrack our way from the helmet cost.
We can form the equation 60 = (x·4) -4, as sheena needs $60, which is four less than (-4) four times her savings (x·4).
Now lets work this problem out
60 = (x·4) - 4
Lets move the 4 to the other side
64 = x·4
Now lets divide by 4
16 = x
Now we know that Sheena has saved $16!
The money did Sheena save is $16.
We need to find the cost of the helmet.
What is the equation?
A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Now, 4x-4=60
⇒4x=64
⇒x=16
Therefore, the money did Sheena save is $16.
