Answer:
<em><u>9 months</u></em>
Step-by-step explanation:
1. write out equation
100 + 22x = 298
2. Subtract 100 from both sides
22x = 198
3. Divide 22 from each side
198/22 = 9

Answer:
The indifference point is 140 minutes.
Step-by-step explanation:
Giving the following information:
Plan A costs $ 25 plus an additional $0.10 for each minute of calls.
Plan B costs $18 plus an additional $0.15 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
<u />
Plan A= 25 + 0.1*x
Plan B= 18 + 0.15*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
25 + 0.1x = 18 + 0.15x
7 = 0.05x
140=x
The indifference point is 140 minutes.
<u>Prove:</u>
Plan A= 25 + 0.1*140= $39
Plan B= 18 + 0.15*140= $39
There were 18 adults on the field trip. See, since 8x6=48, and there are 3 adults in each group, and there are 6 groups, there are 18 adults (6x3=18)
Answer:
18x-16
Step-by-step explanation:
expression: (11x-8)+7(x-1)
ok so what you want to do is combine like terms
but first you are going to distribute
(11x-8)+(7x-8) you distribute the 7
they you can subtract 8 from -8 and that will give you -16
you will then add 11x and 7x which will get you 18x
the final expression will be 18x-16
