Answer:
A. 40.7%
Step-by-step explanation:
The selling price for a $5 profit will be ...
$12.75 +5.00 = $17.75
From $29.95, this represents a change of ...
(17.75 -29.95)/29.95 × 100%
= -12.20/29.95 × 100% ≈ -40.7346%
The bookstore can offer a maximum discount of about 40.7%.
Answer:
10* 299.99=2999.9
2999.9/100=29.999
this would round up to 30, so Brittany saved $30. : )
Step-by-step explanation:
by using similarity and enlargement
10/8 = 7+y/7
70=56+8y
8y=14
y= 7/4
10/8 = 5+x/5
50=40+8x
x = 8/10 = 4/5
i believe it would be: 1/2y = x
y = 2.5
Answer:
y = -5x - 21
Step-by-step explanation:
Given in the question,
equation of a parallel line
y = -5x + 6
point through which it passes
(-4,-1)
Step1
Find the gradient of the equation given, as it is parallel so it will have same gradient
equation of straight line
y = mx + c
where m is gradient
c is y intercept
y = -5x + 6
m =-5
Step2
Find y-intercept
-1 = -5(-4) + c
-1 = 20 + c
c = -20 - 1
c = -21
Step3
form the equation
y = -5x - 21
