EASY 7th GRADE MATH! WILL GIVE BRAINLIEST!

b = 7

Step-by-step explanation:

Step 1: Write out given

cotx° = 3/4

Remember that cot∅ = 1/cos∅

So, tanx° = 4/3

Step 2: Find ratio

tanx° = 2b/10.5

Step 3: Cross-multiply and solve

4(10.5) = 3(2b)

42 = 6b

b = 7

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
