Answer:
Step-by-step explanation:
Adding 2a to both sides
Taking sqrt on both sides
Answer:
1/13, 12/13
Step-by-step explanation:
There are 4 aces in a 52 card deck so P(Ace) = 4 / 52 = 1 / 13.
There are 52 - 4 = 48 cards that are not aces out of the whole 52 cards in the deck so P(not Ace) = 48 / 52 = 12 / 13.
Answer:
10/3
Step-by-step explanation:
110/33
lowest term of 110/33 is 10/3
Answer:
(assuming simple interest)
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
P = deposits
r = interest rate per period (a year)
t = number of periods
P = Php 23,200
r = 0.06
t = 1

Of course you need to know what "gross margin percentage" means.
Roughly speaking it is the profit as a percentage of sale price.
When a unit costs $1.00 and is sold at $2.50 the excess revenue is $1.50
Although we could express this profit margin as a FRACTION of the sale price,
(so this would be 1.50/2.5 = 3/5), it is usual to state this as a PERCENTAGE.
The gross margin percentage in the original case would be 100 * 3/5 = 60%
Let cost price be c, sale price be s.
Gross margin percentage g = 100* (s - c)/s
Solving this for sale price s
s = c/[1 - (g/100)]
When unit cost increases $0.25 we have c = 1.25
so s = 1.25[1 - 0.6] = 1.25/0.4 = 3.1
Action needed to maintain the gross margin percentage
is to increase selling price to $3.10
