Lucy and JoJo need to make 140 cupcakes for the school dance, .
Lucy made 3/5of the cupcakes
• How many cupcakes does JoJo need to make?

56 cupcakes

Step-by-step explanation:

First, I convert 3/5 to a percent because I prefer to work with percents:

3/5 = 0.6 = 60%

Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:

100 - 60 = 40%

Finally, multiply the total cupcakes by the percent as a decimal:

140 × 0.4 = 56

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
