Will Smith paid $857.19 for the 60 inch TV.
Step-by-step explanation:
Step 1:
The 60 inch TV sells for $1,250. The electronics store offers a discount of 35%.
So the price that is paid for the TV is reduced by 35%.
We need to determine how much 35% of $1,250 is.
35% of $1,250
So a discount of $437.50 is applied to the original price.
The discounted price
The discounted price of the TV is $812.50.
Step 2:
A sales tax rate of 5.5% is applied where Will Smith lives.
We need to determine how much 5.5% of $812.50 is.
5.5% of $812.50
So a sales tax of $44.6875 is applied to the original price.
The total price
Rounding this off, Will Smith paid $857.19 for the 60 inch TV.
Answer:
(a) 35.41166
(b) 29.15324
(c) 37.6595
(d) 56.70206
(e) From 1991 to 1998 the change in amount of money circulation decreases and from 1998 to 2011 the change in amount of money circulation increases.
Step-by-step explanation:
The given function is
where t represents the number of years since 1990 and M(t) is in billions of dollars.
Differentiate with respect to t.
.... (1)
M'(t) represents the rate of change of money in circulation, where t represents the number of years since 1990.
(a) For 1991, substitute t=1 in equation (1).
(b) For 1998, substitute t=8 in equation (1).
(c) For 2005, substitute t=15 in equation (1).
(d) For 2011, substitute t=21 in equation (1).
(e) From 1991 to 1998 the change in amount of money circulation decreases and from 1998 to 2011 the change in amount of money circulation increases.
