Answer: 35%
Step-by-step explanation:
Let the original price be "4x".
60% gain on 1/2 of them will be:
(1.60 × 2x) = 3.2x - 2x = 1.2x
20% gain on (1/4) of them will be:
(1.2 × x) = 1.2x - x= 0.2x
Total gain 1.2x + 0.2x = 1.4x
Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%
You simplify both sides and isolate the variable.
Can I get the measures of the figures? I’d be glad to help :))
The slope is 2/3, and the y-intercept is 4. In slope intercept form, the equation is y=2/3x+4
