$550 500/100=5 | 5x2 (2%)= 10 | 10x5=50. 50 added to 500 is 550.
Number of people wearing red pants
= 200/100 x 15
= 30
Those who wear both red shirts and red pants is 30.
Therefore the percentage is
= 30/500 x 100%
= 6%
Multiply .029 and 46. Add the product to 46.
165
7.5 and 5.5 goes to 15x11, and that's your answer. 165.
The answer is C.
If you multiply the top equation by 3 the x variable would become 2x * 3 = 6x
Multiplying the second equation by 2 the x variable becomes -3x * 2 = -6x
You would then have 6x - 6x, which would eliminate the x variable.
