Answer:
Step-by-step explanation:
15 minutes of an hour is 15/60. So 15/60 can be simplified to 1/4.
1/(4a) & 5/(6a)
(3)(1/4a)=3/12a
(2)(5/6a)=10/12a
LCD=12a
Answer and explanation
a is $18.00 because Z is a constant
b is y=2.50x+18.00
c is that y=2.50x+z turns into y=$55.50 and then x=15 which we substitute
that leads to 55.50 =2.50(15)+z
and the untimely z = 18.00 dollars .
