My answer is 22 and 23 and their both integers
Since 1 person costs 50, and for each person after that the cost goes up by $5, we can conclude the following: There is a flat fee of $45 and each guest costs $5.
Since the entry fee is a flat charge and cannot change, and the amount per guest changes based on the number of guests, the variable goes after the 5.
This can be modeled as<em> $45 + $5x</em>. The only options that represent this are A and D. Since he wants his total to be under $100, The correct option would be <u>d. $45 + $5x < 100</u>. Otherwise, with answer A, he would come up with a total that goes over his limit.
Convert the mixed numbers into improper fractions...
-19/3 - (-13/3)
The LCD is 9
-19/9 + 13 * 3/9
-19 + 3 * 13/9
20/9
to mixed number is 2 2/9
Answer is A
12 is the answer hope this helps
-3(1+6x) = 14 - x
-3 -18x = 14 -x
-18x +x = 14 + 3
-17x = 17
x = -17/17
x = -1
Therefore x is equal to -1.
