I’m a bit confused by the choices you have been given. Are there any other options? If not, I would choose (5.3,9.8) as 9.8 is correct
Equivalent rates can be used to compare different sets of quantities that have the same value. A rate that compares a quantity to one is called a unit rate. The unit rate has a denominator equal to one when written as a fraction. Unit rates can be used to find larger equivalent rates.
To find the answer, you have to set each one equal to each other.
(160 + 40x = 55x)
Now, you just solve for X.
55x - 40x = 15x
160 / 15 = 15 / 15x
This means 160/15 = x, or is equal to
10 2/3
