The store has put up a robotics kit on sale for 25% off the original price of $250, AND you have a coupon for an additional 20%

Ganezh [65]

A. If you use only the coupon you will have to pay $137.50.

B. Using the Coupon during the sale, the kit is discounted by $112.50

C. The total percent discount is 45% after both discounts.

Step-by-step explanation:

Step 1; The store has the robotics kit for a sale of 25% off $250. So we need to find how much 25% is in terms of $250. To do that we convert 25% into a fraction by dividing it by 100 and multiplying it with $250.

25% of $250 = $\frac{25}{100}$ × $250 = 0.25 × $250 = $62.50

So we find the cost of the kit due to the store's discount. To do that we subtract the discounted price from the original price.

Robotics kit price after 25% discount = $250 - $62.50 = $187.50.

Step 2; A coupon you have gives you an additional 20% discount. So the robotics kit can be brought for 25% off due to the sale at the store, due to this coupon you get an additional 20%. So you get a 45% discount off $250.

45% of $250 = $\frac{45}{100}$ × $250 = 0.45 × $250 = $112.50.

So to find the total discount we subtract this $112.50 from the non-discounted cost of $250.

Total discounted price = $250 - $112.50 = $137.50.

vaieri [72.5K]

Answer:

$4,012\ senior\ citizen$

$4,012\ infants$

$8,024\ children$

$16,048\ adults$

Step-by-step explanation:

The complete question is

On Saturday,1/8 of the people who visited were senior citizens,1/8 were infants,1/4 were children,and 1/2 were adults.How many of each group visited the zoo on Saturday? It's has to equal to 32,096 people

we know that

1/8 of people were senior citizen

1/8 were infants

1/4 were children

1/2 were adults

To find out how many of each group visited the zoo on Saturday, multiply the total of people by the fraction of each group

$\frac{1}{8}(32,096)= 4,012\ senior\ citizen$

$\frac{1}{8}(32,096)= 4,012\ infants$

$\frac{1}{4}(32,096)= 8,024\ children$

$\frac{1}{2}(32,096)= 16,048\ adults$

Verify

The sum of the total of each group must be equal to 32,096 people

$4,012+4,012+8,024+16,048=32,096\ people$ ----> is correct
