Question

I NEED HEEELPPP ASAPPP

Answer 1

Let $x$ be the number of items.  Each takes 1/8 hour to purchase, so a total time of $\frac 1 8 x$.   If we have 3/4 hour, then

$\frac 1 8 x = \frac 3 4$

That's part a.  

b. Multiplying by 8,

$x = \frac 3 4 (8) = 6$

c. We have time to by 6 items at 1/8 hour each in 3/4 hours.
