So far this basketball season, Sherita made 46 of her
Tresset [83]

Answer:

<em>Sherita would need to make 10 free throws</em>

Step-by-step explanation:

<u>Proportions</u>

Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:

\displaystyle \frac{46}{60}=76.7\%

Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:

\displaystyle \frac{46+x}{60+x}

And we equate it to 80% (0.8 in decimal):

\displaystyle \frac{46+x}{60+x}=0.8

Multiplying by 60+x:

46+x=0.8(60+x)

Operating:

46+x=48+0.8x

Subtracting 46 and 0.8x:

0.2x=2

Dividing by 0.2

x = 10

Jocelyn Angelica bought a dress marked, "Sale Price is 18% Off." The cashier told her she saved $23. How much was the price of t
agasfer [191]

Answer:

$28.05

Step-by-step explanation:

Since the sale price is 18% off, this means we pay 100-18 = 82% of the original price.  82% = 82/100 = 0.82; using x as the original price, we can set up the equation

0.82x = 23

Divide both sides by 0.82:

0.82x/0.82 = 23/0.82

x = 28.05
