For this case you can solve the problem by a simple rule of three:
72 ---> 100%
x ---> 30%
Clearing x we have:
x = (30/100) * (72) = 21.6 $
Then, we must subtract this value from the original price:
72-21.6 = 50.4 $
answer:
Gabriela pays $ 50.4 with the discount

Step-by-step explanation:
Answer:
x>12
Step-by-step explanation:
1/3(x-6)>2
distribute 1/3
1/3x-2>2
add 2 to both sides
1/3x>4
multiply both sides by 3
x>12
F(x) = 8x
y = 8x
x = 8y
x/8 = y
y = x/8
f^-1(x) = x/8
Answer: n-4(32.5) > 300;n > 430tep-by-step explanation:
Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
n-4(32.5) > 300;n > 430tep-by-step explanation:
given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
The minimum profit = 300 + 130 = $430
n-4(32.5) > 300;n > 430 430
