1) 65x .6= 39
39x 1.05= 40.95
Answer: $40.95

2)156.25/50= 3.125
3.125x16=50
x=50

3) 210     42
    ------ = -----
       x       100

210x100= 21000
21000÷42=500

Answer: 1) Final price of the jacket = $40.95

2)  x = 50

3)  Total number of people is 500

Step-by-step explanation:

since we have given that

1) Original price of jacket = $65.00

Discount rate on jacket = 40%

Discount is given by

\frac{40}{100}\times 56\\\\=0.4\times 65\\\\=\$26

So, the price becomes

\$65-\$26\\\\=\$39

Rate of sales tax = 5%

Amount of sales tax is given by

\frac{5}{100}\times 39\\\\=0.05\times 39\\\\=\$1.95

Final price of the jacket is given by

39+1.95\\\\=$40.95

2) \frac{16}{50}=\frac{x}{156.25}

We need to solve for 'x':

\frac{16}{50}=\frac{x}{156.25}\\\\16\times 156.25=50\times x\\\\2500=50x\\\\\frac{2500}{50}=x\\\\x=50

Hence, x = 50

3)Number of people who like football = 210

Percent of people who like football = 42%

Let the total number of people be x

According to question,

\frac{42}{100}\times x=210\\\\0.42x=210\\\\x=\frac{210}{0.42}\\\\x=500

Hence, total number of people is 500.

PLEASE HELP!

We know for the problem that the performer earned $120 at a performance where 8 people attend. We also know that he u<span>ses 43% of the money earned to pay the costs involved in putting on each performance, so we need to find the 43% of $120. To do that, we are going to divide 43% by 100%, and then multiply it by $120:
</span>\frac{43}{100}*120=51.6
Now we know that the performer uses $51.6 of $120 to pay the costs involved in putting on each performance. The only thing left to find his profits is subtract $51.6 from $120:
120-51.6=68.4

We can conclude that the performer makes a profit of $68.4 when 8 people attend his performance.

Laura is planning a party for her son. She has $50 dollars remaining in her budget and wants to provide one party favor per pers
enyata [817]

Answer:

The system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50

Step-by-step explanation:

As the statement says that Laura wants to provide one party favor per person to at least 10 guests, the first inequality would indicate that the number of stuffed animals plus the number of toy trucks should be equal or greater than 10:

x+y≥10

Also, the statement indicates that miniature stuffed animals cost $6.00 each and the toy trucks cost $4.00 each and that Laura has $50. From this, you would have an inequality that indicates that 6 for the number of miniature stuffed animals and 4 for the number of toy trucks would be equal or less than 50:

6x+4y≤50

The answer is that the system of inequalities that represents this situation is:

x+y≥10

6x+4y≤50
