We will solve this by suing simultaneous equations,
⇒ 5s + 3j = 87
4s + 2j = 64
Multiply the first equation with 4 and the second one with 5, this is to get one of the values equal so that we can cancel them out,
⇒ (5s + 3j = 87) × 4
(4s + 2j = 64) × 5
∴ ⇒ 20s + 12j = 348
20s + 10j = 320
Subtract both the equations. This is how your result (after subtraction) should look like,
⇒ 2j = 28
∴ ⇒ j = $14
Now replace the value of 'j' in one of the original equations,
⇒ 4s + 2(14) = 64
⇒ 4s + 28 = 64
⇒ 4s = 64 - 28
⇒ 4s = 36
∴ ⇒ s = $9
Therefore, one pair of jeans cost $14 and a shirt costs $9

Answer:
X=12 on edg
Step-by-step explanation:
X + 4x = 75
Combine like terms:
5x = 75
Divide by 5 on each side of the equal sign:
x = 15
Answer:
Option D.
Step-by-step explanation:
The total stock of currency and other liquid instruments circulating in the economy of a country as of a particular time is known as money supply.
If the reserve requirements of banks is least then banks are able to loan more money, that will increases the overall supply of money in the economy.
In 100% reserve banking system, 100% amount of each depositor's funds would be required to keep by bank for immediate withdrawal on demand.
100% reserve banking system is also known as Full-reserve banking system.
It means, if a customer deposits $100 of currency into a bank with 100% reserve banking system, then the money supply remains the same.
Therefore, the correct option is D.
