Answer:
P = $2448.89
P ~= $2,449
He need to deposit $2,449
Step-by-step explanation:
Given:
Interest rate r= 7% = 0.07
Number of years n = 3 years
Future value that should be meet A = $3000
We need to calculate the initial investment (Principal P). Using the compound interest formula:
A = P(1+r)^n
P = A/(1+r)^n
Substituting the values of A, r, n, we have;
P = 3000/(1+0.07)^3
P = $2448.89
P ~= $2,449
Answer:
5/3 teaspoons (if you don't want an improper fraction, it's 1 2/3 teaspoons)
Step-by-step explanation:
If she uses 1 tsp for 3 cups, then the amount needed for one cup is 1/3 tsp.
Since the mother is using 5 cups, just multiply 1/3 by 5, which equals 5/3.

Step-by-step explanation:
There is a relation of direct proportion between quantity of biscuit and its cost.
Let 200 g biscuit will cost $x.
Therefore,
Answer:
The system of equations are;
4.75t + 7.50b = 790
t = 2b
where t is the number of tacos and b is the number of burritos
Step-by-step explanation:
In this question, we are concerned with writing the system of equations that could help us determine the number of tacos and burritos sold.
Firstly, we start with defining variables. Let the number of tacos sold be t and the number of burritos sold be b
*there we twice as many burritos as tacos sold. What this simply means is that the number of tacos sold is twice the number of tacos.
Mathematically that could be written as ;
t = 2b ••••••••••(i)
Now, let’s work with the revenue;
Each taco is sold at $4.75 and he sold a total of t tacos. The revenue realized from tacos sold is thus $4.75 * t = $4.75t
The money realized from selling b burritos at $7.50 each would be $7.50 * b = $7.50b
The addition of both of these will give the total revenue of $790
Thus, we have;
4.75t + 7.50b = 790 ••••••• (ii)
