Irrational, because it is a repeating decimal.
Answer:
t=2
j=1
Step-by-step explanation:
3 tacos and a juice is $7
3t+j=7
4 tacos and 2 juices is $10
4t+2j=10
We have a simultaneous equation. It can be solved either by substitution method or Elimination method. For the purpose of this question, the elimination method will be used
3t+j=7 Equation 1
4t+2j=10 Equation 2
To eliminate j, we multiply Equation 1 by 2, the coefficient of j in equation 2, so that in both equations, j can have the same coefficient.
2(3t+j=7)
6t+2j=14 Equation 3
We now have
4t+2j=10 Equation 2
6t+2j=14 Equation 3
We subtract equation 2 from equation 3, to eliminate j
6t-4t=2t
2j-2j=0
14-10=4
We have 2t=4
Divide both sides by 2
2t/2=4/2
t=4/2
t=2
Substitute t for 2 in equation 1, to get j
3t+j=7
3(2)+j=7
6+j=7
j=7-6
j=1
One taco cost $2 while 1 juice cost $2

Monthly payments of student loan 25000 at fixed APR of 6% for 15 years is 264 units of money approximately
<u>Solution:
</u>
Given that
Amount of student loan P = 25000
APR = R = 6%
Duration = T = 15 years
First let’s calculate interest on loan.
Interest = 
= 
= 22500
Total amount needs to pay back = Loan amount + interest = 25000 + 22500 = 47500
Duration in which amount needs to be pay back = 15 years = 15 
12 = 180 months
Monthly payment = Total amount needs to pay back / duration in months
= 
= 263.88.
Hence monthly payments of student loan 25000 at fixed APR of 6% for 15 years is 263.888 approx 264 units of money.
X will stand for every extra book sold
880 = 4x + 500
subtract 500 from both sides
380 = 4x
divide both sides by 4
x = 95
they sold 95 books
