Answer:
First number = 25
Second number = 14
Step-by-step explanation:
Let the numbers be x & y
The sum of twice the first and thrice the second is 92
2x + 3y = 92 -------------------(I)
Four times the first exceeds seven times the second by 2
4x - 7y = 2 --------------------(II)
Multiply equation (I) by -2 and then add the equations
(I)*-2 -4x - 6y = -184
(II) <u> 4x - 7y = 2 </u> { Now add, thus x will be eliminated}
- 13y = -182 {Divide both sides by -13}
y = -182/-13
y = 14
Plugin the value of y in equation (I)
2x + 3*14 = 92
2x + 42 = 92
2x = 92 - 42
2x = 50
x = 50/2
x = 25
First number = 25
Second number = 14
In order to find out what the additional value of the sales tax would be,which is 6.5%, you have to find 1% of $245. Which is $2.45. As you're looking for 6.5%, you have to multiply $2.45 by 6.5, which gives you $15.93 (rounded). In order to find the cost including the sales tax, you have to add $15.93 to the original price of $245, which gives you $260.93.
Therefore, the price of the speakers, including a sales tax of 6.5% is $260.93
