Answer:
Here is what I did
Step-by-step explanation:
Answer:
no inglis sorry Xdxdxd y no se entiende xd
<span>You need to set up 2 equations for this, a system to be exact
let x represent the cheaper phone and y represent the upgraded phone
for store costs you will have
5x+25y=200
for selling prices you will have 30x+100y=900
set these two equations together
5x+25y=200
30x+100y=900
multiply the first one by -4 and add them
-20x-100y=-800
30x+100y=900
10x=100
x=10
10 cheaper phones, plug into any equation again
5(10)+25(y)=200
y=6<<<6 upgraded phones</span>
Answer:
x = ±
Step-by-step explanation:
We have been given the quadratic equation;
The first step is to subtract 50 from both sides of the equation;
Multiplying both sides by -1 yields;
The final step is to obtain square roots on both sides;
Therefore, x = ±
