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 situps. For every lunge that he completes, Jacob burns 30 calories. He burns an additional 20 calories for every situp. His goal is to burn at least 620 calories during a workout session. Which is a combination of lunges and situps that Jacob can complete in a session?
7 lunges and 19 situps
11 lunges and 15 situps
10 lunges and 14 situps
12 lunges and 19 situps

Best ResponseYou've already chosen the best response.0So just use the process of elimination? I tried doing that but none of my math turned out to be any answer choice given :/

Best ResponseYou've already chosen the best response.2let 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

Best ResponseYou've already chosen the best response.0Well 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?

Best ResponseYou've already chosen the best response.0yeah that's where i am getting stuck. I keep plugging in all the answer choices but none of them seem to make sense.

Best ResponseYou've already chosen the best response.2i guess it is right not more than 27 and atleast 620 so you can go for B
