A museum opened at 8:00 a. m. In the first hour, 200 people purchased admission tickets. In the second hour, 30% more people purchased admission tickets than in the first hour. Each admission ticket cost $8.50.

Step-by-step explanation:

so 200 times 8.50 is 1,700  and 200 plus 30% was 260 ans 60 times 8.50 is 510 this should help solve it

Step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
