Using linear function concepts, it is found that the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For each car, Cart and Renta, the linear functions are given by:
C(k) = 90 + 0.15k
R(k) = 110 + 0.1k
Cart will cost less than Renta if:
C(k) < R(k)
Hence:
90 + 0.15k < 110 + 0.5k
0.05k < 20
k < 400
Hence, the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

Answer:
28 degrees
Step-by-step explanation:
68 = 2m + 12
56 = 2m
m = 28 degrees
Answer:
$10,000 invested in CD
$18,000 invested in money market
Step-by-step explanation:
<u>Complete Question:</u>
<em>Jorge invested $28,000 into two accounts. The amount he put in his money market account was $2,000 less than twice what he put into a CD. How much did he invest in each account?</em>
Let money put in CD be x
So
Money put in money market will be 2x - 2000
Alltogether, that is 28,000. Thus, we can write:
x + (2x-2000) = 28,000
Solving, we get:
x + (2x-2000) = 28,000
x + 2x - 2000 = 28,000
3x = 30,000
x = 30,000/3 = 10,000
$10,000 invested in CD
We know 2x - 2000 invested in money market, so:
2(10,000) - 2000 = $18,000 invested in money market
Step-by-step explanation:
Thus, option A > is the correct answer.
