Answer:
The price now is 300$.
Step-by-step explanation:
The problem is related to percentages.
It is provided that the price of meal at a restaurant a couple of decades (20 years) ago was 100$.
Now the price is 200% more than what it was 20 years ago,i.e. the price increased by 200%.
Compute the new price as follows:
![New-Price=100\$+[100\$\times200\%]\\= 100\$+[100\times\frac{200}{100}]\$\\ =100\$+200\$\\=300\$](https://tex.z-dn.net/?f=New-Price%3D100%5C%24%2B%5B100%5C%24%5Ctimes200%5C%25%5D%5C%5C%3D%20100%5C%24%2B%5B100%5Ctimes%5Cfrac%7B200%7D%7B100%7D%5D%5C%24%5C%5C%20%3D100%5C%24%2B200%5C%24%5C%5C%3D300%5C%24)
Thus, the price of the meal now is 300$.
To solve this problem, you read the problem backwards and to the opposite of that function.
- if it says double --> divide by 2 22 / 2 = 11
- subtract by 19 --> add 19 11 + 19 =30
- multiply by 5 --> divide 5 30 / 5 = 6
Thus the number that is thought of is 6
Hope that helps!
4 x 1,151.65 = 4,606.60
<span>This is invested in two accounts. Twenty-five percent is invested in savings (4,606.60 x 25% = 1,151.65). The remainder is invested in a CD (4,606.60 - 1,151.65 = 3,454.95) </span>
<span>Interest accrued for savings. *Note: The interest rates given are for a full year, but you want to calculate interest for only 60 days. </span>
<span>1,151.65 x 0.033 x 60/360 = $6.33 </span>
<span>Interest accrued for CD </span>
<span>3,454,95 x 0.043 x 60/360 = $24.76 </span>
<span>Total interest accrued </span>
<span>6.33 + 24.76 = $31.09 </span>
<span>Note: 0.033 and 0.043 = 3.3% and 4.3%. Also, the 360 day year is normally used when doing these types of problems.</span>
The answer would be A because if you combine all the like terms you will get A as a result.
-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.
Hope this helps!!
