Amount of tax paid = 43-40 = 3
Tax rate = 3/40 = 0.75
0.75 x 100 = 7.5%
Tax rate = 7.5%
Answer:
( l+w)
Step-by-step explanation:
just did the question
Group like terms
-4g^4 - 3g^3 + g^2 + 3g^2 + 5g + 9 - 6
combining like terms:-
= -4g^4 - 3g^3 + 4g^2 + 5g + 3
Based on the model, the total amount of money in the joined account after the 5 weeks is $767.30
<h3>What are linear equations</h3>
Linear equations are equations that have constant rates
A linear equation is represented as:
y = mx+ b
In this case,
- m represents the deposit per week
- b represents the initial deposit
So, the linear equations are:
- y =153.46x --- for Monica
- y = 128.90+ 127.68x -- For Lauren
To calculate the number of weeks, when they have the same amount, we equate both equations

Collect like terms


Solve for x

Substitute 5 for x in



Hence, it will take 5 weeks for both accounts to have the same amount of $767.30
