The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))
Answer:
x⁷ = 60
Step-by-step explanation:
<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
- The expotential equation .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Given logarithmic equation is ,
⇒ log x⁵ + log x ¹² = 7
⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]
⇒log x ⁶⁰ = 7
In expotential form we can write it as ,
⇒ x⁷ = 60
I was Thinking it out on my art pad
A=(1/2)
bh A=(1/2)*10*12
A=5*12=60 sq cm
4*60=240 sq cm
A=s*s A=10*10=100 sq cm
240+100=340 sq cm
so A
