please help me correct the wrong answers I dont understand

In 1967, the U.S. minimum wage was $1.40 per hour. In 1975, the minimum wage was $2.10 per hour. Assume the minimum wage grows according to an exponential model w(t), where t represents the time in years after 1960. (a) Find a formula for w(t). (Round values to three decimal places.) w(t) = 0.98e (0.051)t X (b) What does the model predict for the minimum wage in 1960? (Round your answer to the nearest cent.) $ 0.98 (c) If the minimum wage was $5.15 in 1996, is this above, below, or equal to what the model predicts? above below equal X Additional Materials Reading 2/12 Points] DETAILS PREVIOUS ANSWERS UWAPRECALC1 11.P.002. MY NOTES A certain town is experiencing a population boom. In 1990, the population was 870 and five years later it was 1230. (a) Find a linear model /(x) for the population of the town in the year 1990 + x. 1(x) = 72x + 870 Find an exponential model p(x) for the population of the town in the year 1990 + x. (Round values to three decimal places.) p(x) = 870e0.0693x (b) What do these models estimate the population of the town to be in the year 2000? (Round your answers to the nearest whole number.) /(2000) = 1590 people p(2000) = 1739.74 people Additional Materials Reading /9 Points] DETAILS PREVIOUS ANSWERS UWAPRECALC1 11.P.003. MY NOTES In 1989, research scientists published a model for predicting the cumulative number of AIDS cases reported in the United States: a(t) = 155(t - 1980 10 (thousands) where t is the year. This paper was considered a "relief," since there was a fear the correct model would be of exponential type. Use the two data points predicted by the research model a(t) for the years 1986 and 1998 to construct a new exponential model b(t) for the number of cumulative AIDS cases. (Round values to three decimal places.) b(t) = 6443.229( 1.316 ) -1980 (thousands) Discuss how the two models differ and explain the use of the word "relief." relief is used because the presented numbers are cumulative that grow fast when the exponential function is used
