Answer:
26.4 million
Step-by-step explanation:
You multiply the previous summer concert tour attendance by 0.92. In 1988, the attendance was 31 million. 31.1 × 0.92 = 28.6. The attendance in 1989 is 28.6 million. Repeat the step of multiplying by 0.92 to find the attendance in 1990. 28.6 × 0.92 = 26.36 million. Round your answer to the nearest tenth of a million will get you 26.4 million.
