33. Answer: 2×5+3=17
34. Answer: 2×5×3=30
35. Answer: 2×5-3=7
<span>say the amount in jan is x
we know if we subtract off 14.2% of x (from x) we get Feb's amount
so x - 0.142x = 742,513.20
(notice we change 14.2% to 14.2/100 -- that is what % is short for -- or ,as a decimal 0.142)
we have 1x - 0.142x or (1-0.142)x on the left side
0.858 x = 742513.20
</span><span>divide both sides by 0.858 to "solve for x"
</span>
x= <span>865,400</span>
