The future worth (F) of the current investment (P) with the compounded interest of i is calculated through the formula,
F = P x (1 + i)^n
Substituting the known values and the given values,
y = 360(1 + 0.03)^x
Simplifying,
y = 360(1.03)^x
Thus, the answer is letter D.
Solutions
There are two equations in the system of equations in this problem.
Let x = lemonade and y = hot dogs
Equation # 1
x + y = 86
This says that t<span>he vendor sold 86 items.
</span>Equation # 2
2x + 5y = 330
= $2 for each lemonade
= $5 for each hot dog.
= total amount earned is $330.
Only these two equations are true and needed.
Answer:
$8.50 per hour
Step-by-step explanation:
63.75 / 7.5 = 8.5
The price of the watch before the discount is £33.4
<u>Step-by-step explanation:</u>
- Jason bought a watch and a pair of trainers for a total price of £53.55
- The total price he bought has a 15% loyalty discount.
Let us assume,
The original price of the watch and a pair of trainers before the discount = x
- The price 53.55 is less than 15% of x.
- We know that the original price x is 100%
- Therefore, the price 53.55 is 75% of x.

⇒
The original price of a watch and a pair of trainers before the discount is £71.4
It is given that,
Before the discount, the trainer's were priced at £38
Before the discount, the total cost = trainer's cost + price of the watch.
⇒ 71.4 = 38 + price of the watch
⇒ Price of the watch = 71.4 - 38 = 33.4
∴ The price of the watch before the discount is £33.4
