178.09 \times \frac{70}{100}\times \frac{105}{100} = \frac{178.09 \times 70 \times 105}{100\times 100} = \frac{1308961.5}{10000} = 130.89615 \approx \boxed{130.90}

Your answer is $130.90

Note: We multiply by 70/100 because of the 30% discount. 100 - 30 = 70. So we have to multiply by 70%.

Also, we multiply by 105/100 because there is 5% tax. The tax means that we have to pay more which means 100 + 5 = 105.

Hope this helped :D

Since the TV is on sale for 30%, we can either multiply 178.09 by 30% and then subtract that from 178.09, or we can just multiply 178.09 by 70%. The latter is an easier process.

The sales tax is 5%. We can either multiply by 5% and then add this to the total cost, or we can just easily multiply by 105% to make our calculations simpler.

178.09\times \frac{70}{100} \times \frac{105}{100}  = 178.09 \times 0.7\times 1.05 = \boxed{130.90}

The product has decreased by 80 %

<em><u>Solution:</u></em>

The product of the original numbers: xy

One number is decreased by 75 %

Let x be the number decreased by 75 %

new number = x - 75 % of x

new\ number = x - 75 \% \times x\\\\new\ number = x(1-75 \%)\\\\new\ number = x(1-\frac{75}{100}) = x(1-0.75) = 0.25x

Another number is decreased by 20 %

Let y be the number decreased by 20 %

new number = y - 20 % of y

new\ number = y - 20 \% y\\\\new\ number = y(1-20 \%)\\\\new\ number = y(1-\frac{20}{100}) = y(1-0.2) = 0.8y

<em><u>Now the product is given as:</u></em>

product = 0.25x \times 0.8y = 0.2xy

<em><u>Now we have to find the percent decreased</u></em>

Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage

percent\ decrease = \frac{0.2xy - xy}{xy} \times 100\\\\percent\ decrease = \frac{-0.8xy}{xy} \times 100 = -0.8 \times 100 = -80

Here negative sign denotes decrease

Thus the product has decreased by 80 %

The Department of Streets of a city has a budget of $1,962,800 for resurfacing roads and hiring additional workers this year.
ryzh [129]

Answer:

84,000 m + 36,000 p = 1,962,800

Step-by-step explanation:

Let m denotes number of miles of 2-lane roads the department could resurface and p denotes number of workers hired by the department of Streets of a city.

The cost of resurfacing a mile of 2-lane road is estimated at $84,000.

So,

Cost of resurfacing m miles of 2-lane road = $84,000 m

The average starting salary of a worker in the department is $36,000  a year

So,

Total salary paid to p workers = $36,000 p

Now, total amount is equal to $1,962,800.

84,000 m + 36,000 p = 1,962,800
