this week luiz made 80% of what he made last week if he made $72 this week how much did he make last week?

kvv77 [185]

Answer: He made $90 last week.

Assumption :

Let, Luis made $X last week.

He made $72 this week which is 80% of $X that he made last week

⇒ X * 80% = 72

⇒ X * 80/100 = 72

⇒ X = (72 * 100)/80

⇒ X = 90

Therefore, he made $90 last week.

To remember :

While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.

1/3k+80=1/2k+120 k=??

Sati [7]

Answer:

The value of k is 240

Step-by-step explanation:

$\frac{1}{3}k + 80 = \frac{1}{2}k + 120$

Or, 120 - 80 = $\frac{k}{2} - \frac{k}{3}$

Or, 40 = $\frac{k}{6}$

So. k = 40 × 6 = 240

Hence The value of k is 240 Answer

Debora [2.8K]

The second one is the correct equation. The constant to the right should be the diameter squared, while the numbers inside the parentheses should be the opposite.

Tell whether the statement is true or false. If w is 25% of Z, then Z:W is 75:25

melamori03 [73]

False.
If w is 25% of z, then w:z would be 25:100, because 25 is 25% of 100.
If Z:W was 75:25, it would be wrong because 25 is 33% of 75, not 25%.

If it takes 4 men 6hours to repair a road, how long will it take 7 men to do the job if they work at the same rate.

Crank

Tricky question. This isn't a ratio question even though it seems like one.

First divide 7 by 4.
$7 \div 4 = 1.75$

With more men, the hours taken to repair a road will be even shorter.

So next divide 6 by 1.75.
$6 \div 1.75 = 3.43$

Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Hope this helps. - M
