Maddie is participating in the first round a math competition. She writes one contest a month in each of the first ten months of
ad-work [718]

The correct answer is 85 points in each contest

Explanation:

To solve this problem, the first step is to find out how many points Maddie has and then how many points she still needs to get a total of 750 points. Additionally, to do this, the correct process is to multiply the average points by the number of contexts.

In the first five contests, she obtained 68 points average

5 x 68 = 340 points in the first five contests

In the three following contests, she obtained 80 points on average

3 x 80 = 240 points

Now, let's add the points and find how many points she is missing to reach 750 points

340 + 240 = 580

750 - 580 = 170

Finally, let's divide the points missing by 2 because there are still two contests and Madie needs to get the 170 points in these two.

170 ÷ 2 = 85 points

Maddie needs to get 85 points on average to complete her goal of 750 points

A 1-liter bottle of orange juice used to cost $2.85 at a food market. Its price has increased; the new price is 110 percent of t
meriva
Hi there! So, the price is up by 110%. That would mean doubling the price, but that’s not an option. Instead, we can multiply by 110% (1.1) to find the new price of the juice. 2.85 * 1.1 is 3.135 or 3.14 when rounded to the nearest hundredth. The new price of the juice is $3.14. The answer is D.

Sean puts $600.00 into an account to use for school expenses. The account earns 8%
OLga [1]

Answer:

A=\$1,110.56}  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=8\ years\\ P=\$600.00\\ r=8\%=8/100=0.08\\n=1  

substitute in the formula above

A=600(1+\frac{0.08}{1})^{1*8}  

A=600(1.08)^{8}  

A=\$1,110.56}
