You borrowed $200 from your brother and he's created 2 plans to help you decide how you want to pay it back. His plans are below
aniked [119]

Answer:

Question 1

$200

Question 2

Plan A;  The amount payed back per week = $5

Plan B;  The amount payed back per week = $4

Question 3

Plan B

Step-by-step explanation:

Question 1

The amount borrowed from the brother = $200

Question 2

The two plans payment terms created by the brother are;

Plan A,

Amount payed per 2 month = $40/(2 months)

Therefore;

The amount payed per week = $40/(2 months)/((8 weeks)/(2 months)) = $5/week

The amount payed per week for plan A = $5 per week

Plan B

The number of weeks the $200 is payed back = 50 weeks

∴ The amount payed per week = $200/(50 week) = $4/week

Question 3:

The plan to be chosen is Plan B

This is so as to afford enough time to pay back and to have a smaller amount of repayment each week which will reduce the likelihood of defaulting in repayment.

Solve: 6-x =4(5+x)-4
butalik [34]

Answer:

option A , x=-2

Step-by-step explanation:

6-x =4(5+x)-4

6 - x = 4 × 5 + 4 × x - 4

6 - x = 20 + 4x - 4

6 - x = 4x + 16

-x - 4x = 16 - 6

-5x = 10

x = 10/-5

x = -2

therefore, option A is the correct option

hope it helps you
