I'd appreciate it if you were to me! (20 pts)

Your first two tests add up to:

85 + 89 = 174

To average 87 for 3 tests, the tests need to add up to : 87 x 3 = 261

To average 91, the 3 tests need to equal: 91 x 3 = 273

So to average 87, the third test needs to be: 261 - 174 = 87

To average 91, the third test needs to be: 273 - 174 = 99

Your score needs to be between 87 and 99

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

the correct answers i think are b. and d.

give me brainliest if it is correct!
