During a sale, fidget spinners 1/4 off the regular price. if a spinner regularly costs 5.90, what is the sale price

price - (1/4)×price = price×(1 - 1/4) = (3/4)×price

... = (3/4)×5.90 = 4.425 ≈ 4.43 . . . . . sale price

The sale price could be 4.42 if the discount is rounded up, rather than the price being rounded up. If you first compute the discount as (1/4)×5.90 = 1.475 ≈ 1.48, then the half-penny goes to the customer, not the shop-keeper.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
