The coordinates for point a are (-3,5)
The first point tells you the x value and the second tells the y value
y: original price (in dollars)
0.12y: amount of discount (in dollars)
sale price: y - 0.12y = 0.88y
sales tax on this sale price: (0.06)(0.88y)
final cost: 0.88y + (0.06)(0.88y) = 0.88y(1+0.06) = 0.9328y
Answer:
The total number of cupcakes ordered=216
Step-by-step explanation:
The total number of cupcakes ordered that the baker completed can be expressed as;
C=P×t
where;
C=Total number of completed order of cupcakes
P=percentage of order completed
t=total number of ordered cupcakes
In our case;
C=81
P=37.5%
t=t
replacing in the above expression;
81=37.5%×t
(37.5/100)×t=81
t=81×100/37.5
t=216
The total number of cupcakes ordered=216
sum of the cube of a number and 27:
x^3 + 27
