Answer Step-by-step explanation:
Word (story) problems are easy if you use a table to translate the words to precise, concise math variables and operations. For example,
Is means =
Larger than +
Four times a 4*a
F is 550 less than S F = S – 550
Total of A, B, C A + B + C
This seems obvious – until you get stuck on a word problem. So,
“the first company” , “a second company” becomes Let their costs be F and S
Let K be the number of kilograms
“$20 to ship a medium box, plus an additional $2 per kilogram” F = $20 + 2*K
“10 for the same size of box, plus an additional $3 per kilogram” S = $10 + 3*K
“the two shipping methods will cost the same amount” F = S
“What is that weight?” report K
Now, the math:
F = S
20 + 2K = 10 + 3K
$10 = K
