Answer:
a) n = (p + 450) / 30
b) The Minimum number of cakes is 32
Step-by-step explanation:
Given that:
p = 30n - 450, where p is the profit in dollars from selling a number of cakes
(n).
a) to calculate the number of cakes (n) needed to be sold for a given profit, we need to make the number of cakes (n) the subject of formula for the equation.
p = 30n - 450
Adding 450 to both sides:
p + 450 = 30n - 450 + 450
30n = p + 450
Dividing through by 30:
30n / 30 = (p + 450) / 30
n = (p + 450) / 30
b)
If the profit is at least $500, the Minimum number of cakes (n) is:
n > (p + 450) / 30
n > (500 + 450) / 30
n > 950 / 30
n > 31.67
n ≈ 32
The Minimum number of cakes is 32
A function should produce one output for one given input.
Therefore a function should pass the vertical line test.
From the figure,
a,b,c pass the vertical line test;
d fails the vertical line test.
Answer: Case d does not represent a function.
Answer:
$233.95
Step-by-step explanation:
299 x 0.7 = 209.30
209.30 x 1.07 = 233.95
Multiply $72 into 5% and that should give you an answer
Ivan only, because an odd number of negatives does not always make negatives while an even number does.
