I saw the complete problem:
complete the exercise below to decompose 930
930 = _____ tens = ____ x ____
My answer is:
930 = ninety-three tens or 93 tens = 93 x 10

so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on
so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)
thus (0.30x) + (175)(0.65) = (x+175)(0.50)
solve for "x"
