Answer:
x = 2
Step-by-step explanation:
4 - (2x-3) = 3
Distribute the minus sign
4 -2x+3 = 3
Combine like terms
7 -2x = 3
Subtract 7 from each side
7 -2x-7 = 3-7
-2x = -4
Divide by -2
-2x/-2 = -4/-2
x = 2
For decimals, move the decimal point 2 units to the right to get the percentage.
0.125 = 12.5%
0.09 = 9%
for fractions, if it is over 100, make it the percentage of the number
so for 11 over 100, it is 11%
for example, 50 over 100, it is 50%
if it is not over one hundred, divide the numerator to denominator to get a decimal, and then make it into a percentage
for example 11/35. 11 divided by 35 is 0.31
0.31 = 31%
that is just an example
hope this helps

Answer:
Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.
Step-by-step explanation:
Since Tania is buying a guitar, and Guitar Central has 20% off coupons available, and has the guitar Tania wants for $ 349, while Music Mart has the guitar Tania wants for $ 419, but is offering a $ 200 rebate, to determine which is the better deal the following calculations must be performed:
Guitar Central
100 - 20 = 80
349 x 0.8 = X
279.20 = X
Music mart
419 - 200 = X
219 = X
Therefore, Music Mart offers a better deal, given that the price of the guitar is $ 219 compared to $ 279.20 for Guitar Central.
