Answer: he can pay for 6 people total (including him)
Step-by-step explanation:
first lets subtract the flat fee from the total amount of money he has
70 - 40 = 30
now lets divide 30 by $4.50 to see how many people he can pay for
30 / $4.50 = about 6.5
obviously you cant pay for half a person so he can invite 5 people (he also has to pay for himself)
Answer:
$5.73 and $101.23

Answer:
Step by step explanation:
We have been given that Eli is e years old.
Devin is 1 1/4 younger than Eli, therefore, Devin's age in terms of E will be:
We are also given that April is 1/5 as old as Devin. So April's age will be,
Upon simplifying our expression we will get,
Now let us write Jill's age in terms of E.
We are told that Jill is 5 years older than April. So Jill's age will be,
Therefore, Jill's age in terms of E will be .
