Answer:
18 pack
Step-by-step explanation:
Take the cost and divide by the number of bottles
11.21 /18 bottles
.62277777777
62 cents per bottle
15.85/24 =.6604166667
66 cents per bottle
The better buy is 62 cents per bottle
or the 18 pack
Answer:
97/40
Step-by-step explanation:
so 2.125= 17/8
3/10+17/8 need to find common denominator so
times 8/8 to 3/10
times 10/10 to 17/8
24/80+170/80= 194/80 (common denominator so can add)
divide 194/80 because want reduce form
97/40 is the answer
(When i look at it now i can just time 4/4 and 5/5 but its ok this still gets the answer)
Done.
Here is the 6 that I left ==> 6
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
