With mental math, you can perform equations quickly and efficiently. They also help you to develop your own strategies and solve more complex math equations. Hope this helps;)
U=-2b+30
u+b=21
<span>in slope intercept form this is </span>

Answer:
There is money left over. They have 48.98 dollars left.
Step-by-step explanation:
Men costumes in total cost $102.68 and women costumes in total cost $248.34. There budget it $400 so we add both the men and women costumes together which is $351.02 which means that they do have left over money.
