The cloth shop has announced a reduction in price by 25%. How many shirts priced at Rs 28 should buy to avail a total reduction

Drupady [299]

Answer:

At least 6 shirts should be brought to avail a total reduction of Rs 40.

Step-by-step explanation:

The marked price of each shirt = Rs 28

Discount offered = 25%

So, 25% of marked price 28 = $\frac{25}{100} \times 28 = 7$

⇒Reduction on each shirt is Rs 7

Now, total amount reduction needed = Rs 40

So, number of shirts purchased = $\frac{\textrm{Total reduction needed}}{\textrm{Reduction on each shirt}}$

= 40 Rs /7 Rs = 5. 71 ≈ 6

So, at least 6 shirts should be brought to avail a total reduction of Rs 40.

(07.05) Which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x? (4 points) 3x = 9 3x = 1 11x = 9 11x = 1

slava [35]

Okay first you need to combine like terms together (3x and 1x)

7x + 4 = 5 + 4x

now you need x only on one side, you could subtract either 7x or 4x

3x + 4 = 5

subtract 4 over

3x = 1 is the answer
