The Inequality representing money she can still spend on her friend birthday gift is .
Jordan can still spend at most $30 on her friends birthday gift.
Step-by-step explanation:
Given:
Total money need to spend at most = $45
Money spent on Yoga ball = $15
We need to find how much money she can still spend on her friend birthday gift.
Solution:
Let the money she can still spend on her friend birthday gift be 'x'.
So we can say that;
Money spent on Yoga ball plus money she can still spend on her friend birthday gift should be less than or equal to Total money need to spend.
framing in equation form we get;
The Inequality representing money she can still spend on her friend birthday gift is .
On solving the the above Inequality we get;
we will subtract both side by 15 using subtraction property of Inequality.
Hence Jordan can still spend at most $30 on her friends birthday gift.
Answer:
Question 1
Volume of a cylinder = πr²h
r= radius h= height
diameter = 2*radius
diameter = 2* 4cm= 8cm
Volume = π × 4² × 11
= 553.14cm³
Answer:
FV= $436.72
Step-by-step explanation:
Giving the following information:
Initial cost (PV)= $500
Decrease rate (d)= 7% per year
Number of periods (n)= 2 years
<u>To calculate the future value after 2 years, we need to use the following formula:</u>
FV= PV / (1 + d)^n
FV= 500 / (1.07^2)
FV= $436.72
