Answer:
<u>John spends $ 37.98</u>
Step-by-step explanation:
1. John has a bill of $ 32.57
2. He leaves a tip of 18% on the amount before the coupon or tax is applied, in consequence: 32.57 + 18% (32.57) = 32.57 + 5.86 = 38.43
3. He uses a 10% off coupon on the cost of the meal, therefore:
38.43 - 10% (32.57) = 38.43 - 3.26 = 35.17
4. The tax is 8%, then:
35.17 + 8% (35.17) = 35.17 + 2.81 = 37.98
<u>John spends $ 37.98</u>

Answer:
The absolute error of the measurement is 0.25 inches
Step-by-step explanation:
we know that
The absolute error of a measurement is equal to one half the unit of measure.
In this problem we have
7.5 inches
The measurement is given by 0.5 inches
So
the absolute error of this measurement is

Therefore
the exact measurement could be between
7.5 (+/-) 0.25 in
That is, between 7.25 in and 7.75 in
