1st let's calculate r the common ratio:
 r = (-20)/4 = (100/-20) = -5

Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank

Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶

Value of nth term = 62,500

First the store raised the price of a pot by 20%. Then they announced a 20% discount on the pot. Is the customer going to pay mo
andrezito [222]

Answer:

less

Step-by-step explanation:

An increase of 20% makes the price 120% of the original price.

A discount of 20% makes the discounted price 80% of the previous price.

Original price: x

20% increase in price: 1.2 * x

20% discount over the raised price: 0.8 * 1.2 * x

Now we multiply the numbers in the last expression and compare the result with x.

0.8 * 1.2 * x = 0.96x

0.96 is less than x, so the customer pays less than the original price.
