Answer:

1.40 $ per pound.

Step-by-step explanation:

As we go by the statement given:

2x + 3y = 7.20  ..... (1) \\and\\4x + 2y = 8.80  ...... (2)\\\\Now, multiplying \ the\  equation \ (1)\  by\  2\  and\  then\  subtracting\  the\  equation\  (2)\  from\  it.\\(1) \times 2\\ \Rightarrow 4x+ 6y=14.40\\Now, subtracting\ the\ equation\ number (2)\\ \Rightarrow4x + 6y - 4x -2y = 14.40 - 8.80\\\Rightarrow 4y = 5.60\\\Rightarrow y = 1.40Hence, price for oranges is 1.40 dollars per pound.

Luke earned $36,000 during the first year of his job at Putt-Putt Kingdom. After each year he received a 10% raise. Find his tot
Lady_Fox [76]
In order to solve this problem, you need to use a geometric series:
S_{n} =  \frac{ a_{1}(1 - r^{n}) }{1 - r}
where:
a₁ = first term of the series = 36000
r = common rate = 10% raise, therefore 1.10
n = number of terms = 5

Therefore,
 <span>S_{n} =  \frac{ 36000(1 - 1.10^{5}) }{1 - 1.10}
= 219783.60 $

Luke's total earnings in five years are <span>219783.60 $.</span>

Hi there

This is how you read the question: What is the cube root of 64.
To answer this question ask yourself what number multiplied by itself three times gives you the answer 64?
1*1*1=1
2*2*2=8
3*3*3=27
4*4*4=64
YAY! that means the answer is 4. 

Hope this helps.
And you give me the brainliest answer.
Thanks
