Asales report shows that 3300 gas grills were purchased from a chain of hardware stores last year. the store expects grill sales to increase 6% each year. about how many grills does the store expect to sell in year 6? round to the nearest whole number. use an equation, where tt is the number of years elapsed, to justify your answer.

For this case, you must use an equation of the potential type.
 We have then:
 y = A (b) ^ t
 where,
 A: initial quantity of gas grills sold.
 b: increase in sales every year.
 t: amount of time in years.
 We then have to replace the values:
 y = (3300) * (1.06) ^ (6)
 y = 4681.11307
 round to the nearest whole number:
 y = 4681
 
 the store expect to sell in year 6:
 4681 grills
