The compound interest is applied to the remaining balance in the account
each subsequent year.
- The amount that must be deposited is approximately <u>$620.07</u>
Reasons:
The given compound interest rate, r = 6.25% = 0.0625
The balance in the account after 2 years, A = $700
Required:
The required deposit, <em>P</em>, that gives the given account balance after 2 years.
Solution:
The following is the compound interest formula to use;
Where;
t = 2 years
We get;
Which gives;
- The amount that must be deposited to give $700 after 2 years is P ≈ <u>$620.07</u>

I would say that it it "12y represents the value of the truffles." Imean it literally says it in the question but here you go.
The temperature (in k) at which the density of this liquid will be equal to 1.183 g/cm³ is; 639.6 K
<h3>How to find the temperature from density?</h3>
We are given the formula for density as;
D = 1.246 g/cm³/(1 + 8.324 * 10⁻⁵ K⁻¹ × T)
Where D is density and T is absolute temperature (In K).
If we want a density of 1.183 g/cm³, then we have;
1.183 = = 1.246 g/cm³/(1 + 8.324 * 10⁻⁵ K⁻¹ × T)
Cross multiply to get;
1.183 + (1.183 * 8.324 * 10⁻⁵ * T) = 1.246
1.183 + 0.985 * 10⁻⁴T= 1.246
0.985 * 10⁻⁴T = 1.246 - 1.183
T = 0.063/( 0.985 * 10⁻⁴)
T = 639.6 K

Pedro made mistake in step 3.
He supposed to plug in y = 12 into the y in the equation to solve for x
Should be:
-14x - 2(2)=24
-14x - 4 = 24
-14x = 28
x = -2
Answer:
39 students
Step-by-step explanation:
let x represent the number of students taking both current event and foreign language
there are : 70 eight grader taking current event and 54 taking foreign
70+54-x=93
-x=93-124
x= 31 students taking both
number of eighth graders take only a current events class and not a foreign language class: 70-31=39 students
