The answer choice is B. 50 dollars per month.
50 times 3 is 150 and 50 times 6 is 300.
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1)
we know that
The equation of the line in slope intercept form is equal to

we have

Isolate the variable y
subtract 2x both sides

Divide by B both sides

Part 2)
we know that
The equation of the line in slope intercept form is equal to

we have

Isolate the variable y
subtract 2x both sides

Divide by 8 both sides

Simplify

Answer:
Point D
Step-by-step explanation:
Using a system of equations, it is found that £52 was originally shared.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: Angela's share.
- Variable y: Michelle's share.
- Variable z: Daniel's share.
Angela and Michelle shared some money in the ratio 4: 9, hence, considering t as the total:
.
Angela gave Daniel half her share.Michelle gave Daniel a third of her share. Daniel was given a total of £20, hence:



30t = 20 x 78
t = 20 x 78/30
t = £52.
