Answer:
you can cross multiply or u can 7/20 to get the answer that 7 is 35% of 20
$1.75
If 4 lemons altogether cost $7, you want to divide the price by 4 to find the price for one single lemon.
7/4 = $1.75
Now if you buy 4 lemons that cost $1.75, your total will add up to $7
The problem here is: Too many words.
If you boil the problem down to the bare facts, the question is:
"$210 is 15% of what number ?"
I'm pretty sure you can take it from there,
but here's the rest of it anyway:
$210 = 15% of (March amount)
$210 = 0.15 x (March amount)
Divide each side by 0.15 : $1400 = March amount .
Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!
3x - 5 = -26
<u>step 1:</u>
subtract +5 on each side because you have to do the inverse operation
<u>step 2:</u>
3x= -21
<u>step 3:</u>
now divide 3 on each side
the answer is -7
