Answer:
9y + 4z + 9x
Step-by-step explanation:
1$ = 100 cents, 1 hour = 60 minutes
$3.00/hour = (3*100) cents / (1*60)minutes
= 300 cents/60 minutes
= 5 cents/minute
Option b.
Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.
