Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then

i.e. For 10 sessions, the cost of the two plans the same.
8x-9y=11
Add 9y to both sides
8x = 11 + 9y
Subtract 11 on both sides
8x - 11 = 9y
Divide 9 on both sides
Answer:
Let Craigs age = x
Therefore Dianes age = 25 + x ( since she's 25 years older)
Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)
25 + 2x = 105
2x = 80
x = 40
Craigs age is 40 years old.
Dianes age is 65 years old.
Answer:
3months
Step-by-step explanation:
target $1100
currently saved $1100
so we get the amount she need to save to get to the target.
$1100 - $110= $990 Need to be saved
saving rate 10% of $3300= $330 per month
to get the number of months she need to save, we divide amount needed by amount saved per month; $990 ÷ $330= 3months
