Answer:

1. 7^(x-y)

2. z^5x^y

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

$\dfrac{7^x}{7^y}=\boxed{7^{x-y}}$

$\dfrac{z^{10}x^y}{z^5}=x^yz^{10-5}=\boxed{z^5x^y}$

The cost price of 18 sweaters is Rs425 per sweater and the total gain of the shopkeeper is Rs 6,750 1 find the sale price of eac

Nostrana [21]

Answer:

1. Sales price per sweater= Rs 800

2. percentage = 46.875% = 46.88%

Step-by-step explanation:

Given;

Cost price = Rs425 per sweater

Number of sweaters = 18

Total gain = Rs 6,750

Total cost price = cost price × number of sweaters

Total cost price = 18 × Rs425 = Rs 7,650

Total sales price = total gain + total cost price

Total sales price = Rs 6,750 + Rs 7,650

Total sales price = Rs 14,400

Sales price (per sweater) = Rs 14,400/18 = Rs 800 per sweater

Profit percentage = total gain/total sales price × 100%

Profit percentage = Rs 6,750/Rs 14,400 × 100%

Profit percentage = 46.875% = 46.88%
