Answer:
seven-eighths of a number minus three
Explanation:
the algebraic expression given to us is:
we have seven-eighths multiplied by a number "y" (this can also be expressed as seven-eighths of the number) and then, to that we substract 3 (minus three).
With this information we can conclude that the phrase that best describes this expression is:
seven-eighths of a number minus three
which is the first option.
