How do you work a percentage problem

Slav-nsk [51]

Answer:

Some percents are easy to figure. Here are a few:

Finding 100% of a number: Remember that 100% means the whole thing, so 100% of any number is simply the number itself:

100% of 5 is 5

100% of 91 is 91

100% of 732 is 732

Finding 50% of a number: Remember that 50% means half, so to find 50% of a number, just divide it by 2:

50% of 20 is 10

50% of 88 is 44

Finding 25% of a number: Remember that 25% equals 1/4, so to find 25% of a number, divide it by 4:

25% of 40 is 10

25% of 88 is 22

Here’s a trick that makes certain tough-looking percent problems so easy that you can do them in your head. Simply move the percent sign from one number to the other and flip the order of the numbers.

Suppose someone wants you to figure out the following:

88% of 50

Finding 88% of anything isn’t an activity that anybody looks forward to. But an easy way of solving the problem is to switch it around:

88% of 50 = 50% of 88

This move is perfectly valid, and it makes the problem a lot easier. As you learned above, 50% of 88 is simply half of 88:

88% of 50 = 50% of 88 = 44

As another example, suppose you want to find

7% of 200

Again, finding 7% is tricky, but finding 200% is simple, so switch the problem around:

7% of 200 = 200% of 7

Above, you learned that to find 200% of any number, you just multiply that number by 2:

7% of 200 = 200% of 7 = 2 7 = 14

Hope this helps you!!

Pls answer this asap

denis23 [38]

Answer:

y = - $\frac{3}{2}$ x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = $\frac{0-3}{2-0}$ = - $\frac{3}{2}$

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - $\frac{3}{2}$ x + 3 ← equation of line

Linda Murray's investment earned $77.00 in simple interest in 6 months at an annua

Greeley [361]

Answer:

$\$2,200$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=6/12=0.5\ years\\ P=?\\ I=\$77.00\\r=7\%=7/100=0.07$

substitute in the formula above

$77.00=P(0.07*0.5)$

solve for P

$77.00=0.035P$

$P=77.00/0.035$

$P=\$2,200$
