Answer:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
-37/5= y
4x-3(-37/5)=31
x=11/5
Answer:
$130
Step-by-step explanation:
Cost = 85
To make 30% profit, he would need to sell them at:
85 + (0.3)(85) = 110.5
Now, he would need to sell them at 110.5 AFTER giving a 15% discount. So essentially we are asking, "<em>What number discounted (decreased) by 15% would give us 110.5??"</em>
<em />
We can let that price be x and write the equation:
x - (0.15)(x) = 110.5
x - 0.15x = 110.5
0.85x = 110.5
x = 110.5/0.85 = 130
The retailer should mark the jacket at $130
35/35-14/35=21/35=0.6=60%
