Sample question:
Aimee bought 2 CDs each costing $11.95 and 3 CDs each costing $6.48. She paid with a $50 note. How much change did she receive?
Answer:
2 × 11.95 = 23.9
3 × 6.48 = 19.44
Total spent = 23.9 + 19.44 = 43.34
Change = 50 - 43.34 = $6.66
If the table is:
x | y
------
1 | 76
------
2 | 92
---------
3 | 108
-----------
4 | 124
-------------------------------------------------------------------------------------------------------------------
Find the change inbetween each amount per week
92 - 76 = 16
108 - 92 = 16
etc.
This means that her initial deposit should be subtracting 16 from her first deposit.
76 is the amount first deposited
76 - 16 = 60
A) $60 should be your answer
hope this helps

Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a → (1)
(4, 162)
162 = a → (2)
divide (2) by (1)
= = 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2 ← exponential equation
