Answer:

Fri. $10

Sat. $40

Sun. $20

Step-by-step explanation:

earnings on Saturday=x

Sunday is .5*x, which is 1/2 of Saturday

Friday is .25*x, which is 1/2 of Sunday

x+.5x+.25x=70

(simplify)1.75x=70

Divide by 1.75       1.75x/1.75=70/1.75

X=40

then plug in x for all days

1. Slope = rate of change

Since it’s only one year
You can subtract 36 from 40

Solution: the slope is 4

2. Months increase the most, the lines which are steeper and going upward (since it’s increasing)
Solution: from 2015 to 2016

What is the number whose 4/5 is 144
Savatey [412]

We want 4/5 of a number to be 144. This means that

\dfrac{4}{5} \cdot x = 144

Multiplying both sides by 5/4, we have

x = \dfrac{144\cdot 5}{4} = 180
