David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2: = (–8.3)(–2) + (–8.3)(–0.5)
Step 3: = (–16.6) + (–4.15)
Step 4: = –20.75

In which step did David make his first error?
Step 1
Step 2
Step 3
Step 4Based on what you have just read, why is studying atoms and their parts and particles helpful to people?

∠cbe and ∠deb are same-side interior angles.

i took the test

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
