Jackson is on a new exercise regimen. To begin, his trainer does not want him to complete more than a total of 27 lunges and sit-ups. For every lunge that he completes, Jacob burns 30 calories. He burns an additional 20 calories for every sit-up. His goal is to burn at least 620 calories during a workout session. Which is a combination of lunges and sit-ups that Jacob can complete in a session?
7 lunges and 19 sit-ups
11 lunges and 15 sit-ups
10 lunges and 14 sit-ups
12 lunges and 19 sit-ups

Cool thanks, I will try and figure out some if I can with that equation. Thanks.
So just use the process of elimination? I tried doing that but none of my math turned out to be any answer choice given :/
Not the answer you are looking for? Search for more explanations.
whats so funny dude?
let me explain
so the answer is b?
Go ahead you can probably help her way more that I can.
let lunges = x and sit ups = y
so his trainer has said not to do total more than 27
so x+y =27
and he should burn atleast 620 calories
so 30 calories for lunges and 20 for situps
so you have 30x+20y =620
solve these 2 equations
you will get answer
Goodness...I knew how to do that and totally forgot about the other equation :P Lol I always do stuff the hard way cause i forget the easier way.
i am not so good at substitution but I am leaning towards answer choice b. am i correct?
what will you do if there are no options given
Well I work backwards a lot, so I guess I will fail. I know I need to practice more. but for now, I just wanna get this review done :) and make sure I am ready for my exam tomorrow.
you cant solve the equations
then are you?
okay do this
put value of x in 2nd equation and find y
Well now i am doubting myself. I worked through the steps and 630 is what i got. So. am i right? about the answer being b?
11+25 = 26
well none of them totals 27 :|
yeah that's where i am getting stuck. I keep plugging in all the answer choices but none of them seem to make sense.
i guess it is right
not more than 27 and atleast 620
so you can go for B
