Answer:
A: [2(200-x)]/3 B: 31.33333...
Step-by-step explanation:
A: Algebraic expression:
Let's say average = x
So the expression is [2(200-x)]/3
You have to take average away from 200, which is 200-x, you have to multiply that whole expression by 2, and then divide everything by 3.
B: Plug in 153 for x:
2(200-153)/3 and then just solve algebraically
=2(47)/3
=94/3
=31.33333...

Estimate Tip = $4.50
Step-by-step explanation:
The bill to the nearest $10 is $30.00 : ( $ 30 ($32.43) $40, it is nearer to $30
Estimate Tip = Bill rounded to the nearest $10 × Tip %
Estimate Tip = $30 × 15%
Estimate Tip = $30 × .15 (15% change to a decimal is .15)
Estimate Tip = $4.50
