Answer:
Step-by-step explanation:
The interval [4, ∞) all real numbers 4 and greater, whereas the interval (4,∞) not includes the endpoint 4.
So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5
change the 2/5 into decimals by 2 ÷ 5 = 0.4
multiply $55 with 0.4
55 x 0.4 = 22
so she ends up saving $22
v = w - 20
move -20 to the other side
sign changes from -20 to +20
to get w by itself
v+20= w-20+20
Answer:
w= v+20 or w= 20+v
The answer is going to be 7/8. hope that helped
