Step-by-step explanation:
Part A
The function representing the amount of money in account A after x years is represented by the function
f(x) = 9,628(0.92)x
The amount of money in account A is decreasing by 8% per year.
Part B
The table showing the amount g(r), in dollars, of money in account B after r years with number of years given as 1 2 3 4 and amount in dollars) 1,375 1,512.50 1,663.75 1,830.134.
Looking at the table,
The change per year is
(1512.5 - 1375)/1375 = 137.5/1375 = 0.1
The percentage change is 0.1× 100 = 10%
The amount in account B increases by 10%
Therefore, account B recorded a greater percentage change in amount of money over the previous year since the change in account B is 10℅ which is greater than 8% in account B
3 + 3 + 3 + 3 + 5 + 5 = 22
the perimeter is 22 cm
Round each addend to the nearsest ten thousand, and then find the estimated sum for 337,961 + 482,746 = 820,707

Step-by-step explanation:
Conclusion: young people like condiments.
First, let's convert things into percentages, since the number in each age category is different. There are 143 in "Under 18", 233 in "18 to 40", 161 in "40 to 60", and 122 in "over 60".
Of the under 18s: 71 of 143 = 49.7% order three or more.
Of the 18-40s: 87 of 233 = 37.3% order three or more.
Of the 40-60s: 47 of 161 = 29.2% order three or more.
Of the 60 and ups: 28 of 122 = 23.0% order three or more.
The older you are, the less likely you are to order lots of condiments.
