Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
where
y is the average annual salary

substitute
For x=4 years
Answer:
Edison will be paid $15,112 for 3 months
Step-by-step explanation:
Edison receives an annual fixed pay = $45,448.
Monthly pay = 45,448/12 = $3787.33
3-month salary = $3787.33 *3 = $11.362
Commission = 15%
Total sale = $25,000 for the first 3 months.
Commission amount = 25,000*0.15 = $3750
Therefore, total pay that Edison received during first 3 months= salary + commission
= $11,362 + $3750
= $15,112
Thank you.

I got this by doing 8+3=11
110÷11=10
8×10=80
3×10=30

Answer: the cost of one package of macadamia nut chip cookie dough is $1.5
the cost of one package of triple chocolate cookie dough is $2.5
Step-by-step explanation:
Let x represent the cost of one package of macadamia nut chip cookie dough.
Let y represent the cost of one package of triple chocolate cookie dough.
Mrs. Julien’s class sold 25 packages of macadamia nut chip cookie dough and 30 packages of triple chocolate cookie dough for a total of $112.50. This means that
25x + 30y = 112.5 - - - - - - - - - - - - -1
Mrs. Castillejo’s class sold 8 packages of macadamia nut chip cookie dough and 45 packages of triple chocolate cookie dough for a total of $124.50. This means that
8x + 45y = 124.5 - - - - - - - - - - -2
Multiplying equation 1 by 8 and equation 2 by 25, it becomes
200x + 240y = 900
200x + 1125 = 3112.5
Subtracting, it becomes
- 885y = - 2212.5
y = - 2212.5/- 885
y = 2.5
Substituting y = 2.5 into equation 1, it becomes
25x + 30 × 2.5 = 112.5
25x + 75 = 112.5
25x = 112.5 - 75 = 37.5
x = 37.5/25 = 1.5
The method used is the elimination method. It is more convenient to use.
