I really think it’s Senior because it has the highest Average score.
So here is how we are going to answer the problem above:
Given that f is the cost of French fries and b is the cost of Hamburger.
So: 5f + 6b = 4.55
5f = 4.55 - 6b (multiply both sides by 6) and we get
30f = 27.3 - 36b
Next,
6f + 10b = 7.00 (multiply both sides by 5) and we get
30f + 50b = 35 (Now substitute the value of 30f)
27.3 - 36b + 50b = 35
14b = 35 - 27.3
14b = 7.7 (divide both sides by 14)
b = 0.55
Therefore, the cost per hamburger is $0.55
Now go back to the cost of fries:
30f = 27.3 - 36b
30f = 27.3 - 36(0.55)
30f = 27.3 - 19.8
30f = 7.5 (divide both sides by 30)
f = 0.25
Therefore, the cost per french fries is $0.25
Hope this helps.
When the x-value has increased by 1 unit, the y-value has multiplied by 3, so we expect a function of the form (something)×(3^x). The last choice has that.
... f(x) = 4(3)^x

You can always evaluate the offered choices at the given points to see which of them works. The second point (2, 36) will tell you the fastest.
4·3^-2 = 4/9 ≠ 36 . . . . . you can tell at this point you don't want -x as the exponent
3·4^-2 = 3/16 ≠ 36
3·4^2 = 48 ≠ 36
4·3^2 = 36 = 36 . . . . this is the one you want
1) Simplify : - 4x + 3(2x + 5) - 3x + 12
breaking 3(2x + 5) we get,
Now, as per the PEMDAS rule let's shorten the like terms
<u>Correct option is C i.e. - x + 27</u>
2) Simplify : 3x + 3(x + 6) - 4 - 5x
breaking 3(x + 6) we get,
Again using the same rule we see,
<u>Correct answer is option C i.e. x + 14</u>
3) Expression : y[x² - 2(1 + 2)] ÷ y + 5²
In this case we are given that <em>x = 3</em> whereas <em>y = 7</em>
Putting the values of x and y we see,
<u>Henceforth, the final answer is 28</u>
