Vedmedyk [2.9K]

Answer: 960 calories

Step-by-step explanation:

Given

Each hamburger has 50 more calories than each order of fries

Suppose each order of fries has $x$ calories

so, hamburger has $x+50$ calories

There are total of 1700 calories available. Thus, we can write

$\Rightarrow 2(x+50)+3x=1700\\\Rightarrow 2x+3x=1700-100\\\Rightarrow 5x=1600\\\Rightarrow x=320$

So, each order of fries has $320$ calories

For 3 orders, it is $320\times 3=960$ calories
