Answer:
what is this for?
Step-by-step explanation:
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
y= 1/10x - 6
Which if you plug in 70 for x, y equals 1.
Rebecca has $1 and Tim has $70, together they have $71.

You are taking two times a number, which is defined as x. That is equivalent to 2x. Then, you are adding three more to that product.
