Answer:
x = 11.5
Step-by-step explanation:
The cost of 15 passes = 15 × 1.5 = 22.50
The cost of the student card = 29.50 - 22.50 = $7.00
Answer:
Total amount that Matthew's bank will receive is $10099.81.
Step-by-step explanation:
We need to find the amount Matthew's bank will receive after lending him $8,000 for four years at an interest rate of 6 percent, compounded annually.
The formula for compound interest is:
Where A = future value
P= Principal Amount
r = interest rate
and n= time
So in the question we are given:
P= $8000
r = 6% or 0.06
t = 4 (since 4 yeras compounded annually)
A= 8000*(1+0.06)^4
A= 8000*(1.06)^4
A= 10099.81
So, total amount that Matthew's bank will receive is $10099.81.
Answer:
13/4, 3 1/4, or 3.25
Step-by-step explanation:
Using a system of equations, it is found that 22 flowers are in George's garden.
<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 <em>variables </em>are:
- Variable x: Number of red flowers.
- Variable y: Number of blue flowers.
- Variable z: Number of yellow flowers.
All the flowers are red except 14, that is, there are 14 that are blue or yellow, hence:
All are blue except 18, that is, there are 18 that are red or yellow, hence:
All are yellow except 12, that is, there are 12 that are red or blue, hence:
From the first two equations:
Since
The total amount of flowers in the garden is:
