R=0.05×100=5%
Hope it helps
Answer:
a) p(t) = 8.25t - 5
b) p(11) = 90.75 - 5 = $85.75
Step-by-step explanation:
During a clothing store's Bargain Days, the regular price for T-shirts is discounted to $8.25. This means the new price of a T-shirt is $8.25 if it is bought during the clothing store's bargain days. Also, there is additional coupon for $5.00 off, regardless of how many shirts are purchased. This means $5 off the total amount that you pay for the T-shirts.
a) the rule for the function, p(t) that expresses the final price of t T-shirts with the discount applied would be
p(t) = 8.25t - 5
Where p(t)= the final price of t T-shirts
t = number of T-shirts.
b) During the bargain days, amount paid for 11 T-shirts would be
p(11) = 8.25×11 - 5
p(11) = 90.75 - 5 = $85.75
It seems like u are correct, smart man

Answer:a=1 b=5 c=9
Step-by-step explanation:
-7,-3,a,b,c,...... Is the arithmetic sequence
first term=p=-7
Common difference=d=-7-(-3)=-4
a is the 3rd term=-3+4=1
b Is the 4th term=1+4=5
c is the 5th term=5+4=9
Therefore
a is 1
b is 5
c is 9
