Amanda exercised for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week.Billy exercised for 5 minutes every day in the first week, 10 minutes in the second week, 20 minutes in the third week, and 40 minutes in the fourth week.
Which statement best describes the methods used by Amanda and Billy to increase the time they spent exercising?
A) Amanda's method is linear because the number of minutes increased by an equal number every week.
B) Billy's method is linear because the number of minutes increased by an equal factor every week.
C) Both Billy's and Amanda's methods are exponential because the number of minutes increased by an equal factor every week.
D) Both Billy's and Amanda's methods are exponential because the number of minutes increased by an equal number every week.

Answer:
A) Amanda's method is linear because the number of minutes increased by an equal number every week.
Step-by-step explanation:
Amanda's method is linear because the number of minutes increases by an equal number of minutes every week, that is 10 minutes.
1st week 0 + 10 = 10
2nd week 10 + 10 = 20
3rd week 20 + 10 = 30
4th week 30 + 10 = 40
Whereas Billy's equation forms like where x is weeks.
Each week Billy is increasing his time two times or double.
So, Amanda's method is linear and Billy's method is exponential.
Option A is correct.

The 'minus sign' ( - ) before the parentheses says that in order to
get rid of them, you have to change the sign of each term inside.
-3a - (5 - 6a) is the same as
-3a -5 + 6a
Add up the (-3a) and the (+6a) and you have +3a .

168/50= 3.36
Final answer:
To find the average sales rate of cupcakes per customer, you divide the total number of cupcakes sold (168) by the total number of customers (50). The result is approximately 3.36 cupcakes per customer.
Explanation:
To answer this question, you need to understand the concept of a rate, which is a ratio that compares two different kinds of units. Here, the units are the number of cupcakes sold and the number of customers.
Firstly, note that a 'dozen' equals 12. So the shop sells 14 dozen, or 168 cupcakes every day.
To compute the rate, you divide the total number of cupcakes by the number of customers: 168 cupcakes รท 50 customers = 3.36 cupcakes per customer. So, on average, each customer at the shop buys approximately 3.36 cupcakes.
