It is the first option because if we go by the formula y=mx+b; m is the slope (which is equivalent between both lines) and then b is the y-intercept and we can see that the blue line intersects at approximately 1 and the red line intersects at approximately-3 so this makes it so that the best option is the first one

Taylor has saved $99 for a tablet. That is 45% of the cost of the tablet. How much does the tablet cost?

gayaneshka [121]

Answer:

$220

Step-by-step explanation:

Make a proportion

We know that 99 over some number (x) must equal 45%

99/x=45/100

Cross multiply

45x=9,900

Divide by 45 on both sides

x=220

So, the tablet costs $220

Hope this helps! :)
