Brian is remodeling his standy. He bought a desk for $437.50, a chair for $92.75, a filing cabinet for $99.99, and a bookshelf for $309.75. He bought everything at the same store and paid a 7 percent sales tax. How much did he spend on his study?

He spent $1005.7893 on his study

Step-by-step explanation:

At first, let us find the total of all items he bought

∵ The price of the desk = $437.50

∵ The price of the chair = $92.75

∵ The price of the filing cabinet = $99.99

∵ The price of the bookshelf = $309.75

→ Add all of them up

∴ The total price = 437.50 + 92.75 + 99.99 + 309.75

∴ The total price = $939.99

∵ He paid a 7 percent sales tax

∴ The tax = 7%

→ If the total price is 100% add it by 7% to find the amount that he paid

∵ The total price after added the sale tax = 100% + 7% = 107%

∴ He paid = 107% of $939.99

∴ He paid = × 939.99

∴ He paid = 1005.7893

∴ He spent $1005.7893 on his study

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
