Shawna's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 10 senior citizen tickets and 13 child tickets for a total of $87.60. The school took in $63.40 on the second day by selling 11 senior citizen tickets and 4 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.​

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

y + 11 = (1/4)(x + 16)
