I think the answer varies, depending on how the question is worded.
Here's how I got it:
In PEMDAS, you must do the work in parenthesis first. 60 plus 7 is 67, and 4 times 67 is 268, so there are a variety of answers.
You could do 200 + (60+8), and the answer would be 268.
You could do 100 + (110+58), and the answer would be 268.
You could even do 1 + (200+{60 + [4+4] } ), and the answer would be 268.
It depends on what the answer choices are, really. If it isn't an answer choice question, you got three answers right off the bat.
Answer: I think the last option is the correct answer.
Step-by-step explanation:
A) let x=months let y=cost
y=mx+b
y= 20x+ 60
Remember 20 is the variable which means in this case every month it cost 20$ and 60 is the constant which means you only pay it once
B) let x= Months let y= cost
y=10x + 150
C) platinum gym
y= 20x+60
y=20(1)+60
y=20+60
y=80
Superfit
y=10x+150
y=10(1)+150
y=10+150
y=160
Therefore Tom will pay less after the first month
D) y=y solve for x
y=20x+60
y=10x+150
20x+60=10x+150
-10x. -10x
10x+ 60=150
-60. -60
10x=90
10x/10=90/10
X=9
9 months
Pick any equation and sub in x
Y=10x+150
Y=10(9)+150
Y=90+150
Y=240
240$
Know that you only have to do one equation to find y but if you want to show both you can
Therefore there is a period where Tom and Edward paid the same amount, after nine months they would both pay $240
E) if they plan on going to the gym 9 months and less the best deal gym is platinum gym but if they want to go for more then 9 months then the best deal gym is super fit
Y=4x-18 is the parallel equation
Y=mx+b Substitute
2=4(5)+b Multiply by 5
2=20+b Substract 20 in both sides
-18=b
Answer:
56
Step-by-step explanation:
Just substitute 7 for p in the expression 9p - 7: 9(7) - 7 = 56
