65 = 350/5 - 2e
Solve for e.
One of the qualifications for a job is a typing speed of at least 65 words per minute. If Jordan knows that she will be able to type 350 words in five minutes, what is the maximum number of errors she can make?
A.0
B.2
C.3
D.4
Please help me and show your work.
Solve for e.
S = w/5 - 2e
We know that Jordan wants her typing speed to be at least 65 words per minute (S ≥ 65) and she plans to type 350 words in 5 minutes (w = 350). We need to find the value of e.
Substituting these values into the equation:
65 ≤ 350/5 - 2e
Multiplying both sides of the inequality by 5:
325 ≤ 350 - 10e
Rearranging the terms:
10e ≤ 350 - 325
10e ≤ 25
Dividing both sides of the inequality by 10:
e ≤ 25/10
e ≤ 2.5
Since e represents the number of errors, it cannot be a non-integer value. Therefore, Jordan can make a maximum of 2 errors (B) while still meeting the requirement of at least 65 words per minute.
