Question

At a lunch stand, each hamburger has $50$ more calories than each order of fries. If $2$ hamburgers and $3$ orders of fries have a total of $1700$ calories, how many calories does a hamburger have?

• A. $370$
• B. $270$
• C. $340$
• D. $240$

Answer 1

The correct option is A $370$

Assuming a hamburger has $h$ calories, then the number of calories in fries $=h-50$
Given, $2\left(h\right)+3(h-50)=1700$
$=>2h+3h-150=1700$
$=>5h-150=1700$
$=>5h=1850$
$=>h=370$
