2 minutes 30 seconds, or 2:30.
If two customers enter the store every five minutes, that means you have to divide 5 minutes by 2 to get the amount of time it takes for each customer to enter.
Answer:
Step-by-step explanation:
Original cost = $55
Current price = $40
Decrease in price = 40-55 = -$15
Percentage decrease = [(New price - old price)/ old price] *100
Percentage decrease = (40-55)/55] *100
= -0.272727 *100
= -27.27%
To a whole percentage = 27%
Therefore, the cost of the t-shirt decreased by 27%

ANSWER
(5r^2 - 6)(2r - 5)
EXPLANATION
Factor by grouping
(10r^3 - 25r^2) + (-12r + 30)
Factor a GCF
5r^2 (2r - 5) -6 (2r - 5)
Combine groups
(5r^2 - 6)(2r - 5)
CHECK
Use FOIL
First: 5r^2*2r = 10r^3
Outside: 5r^2*-5 = -25r^2
Inside: -6*2r = -12r
Last: -6*-5 = 30
