A. Sam purchased 3 games for $140 after a discount of 30%. What was the original price?
Semmy [17]

Answer:

a) $175 b) It will be $126

Step-by-step explanation:

Cost price of 3 games= $140

Let the original price of games= $ x

Discount is given= 30%

According to question

x \frac{(100-20)}{100}= $140

x \frac{80}{100}= $140

x ×0.8= $140

x= $ \frac{$140}{0.8}

x= $175

Hence, the original price of games $ 140

(b)  If Sam had given a discount of 20%

Again a discount = 10%

The price of games=$ 140

Now, the selling price will be= 175\frac{(100-20)}{100}×\frac{(100-10)}{100}

Now, the selling price will be= $ 126

Hence, the price will be different.

Question 5 (1 point)
ElenaW [278]

Answer:

The volume of the shape is 560 ft^3

Step-by-step explanation:

To find the volume of the figure, we need to multiply the base area by the height of the figure

mathematically, we have the base area as a rectangular shape and its area is the product of its side lengths

We have this as 8 ft * 10 ft = 80 ft^2

So multiplying this by the height which is 7 ft, we have this as;

7 ft * 80 ft^2 = 560 ft^3
