Jessica is selling tickets for her softball team for $10 a ticket. Laurie is selling tickets for her softball team for $6 a ticket and has already saved $360. If they sell the same amount of tickets, how many tickets do they have to sell for the money to be equal

90 tickets

Step-by-step explanation:

let the number of tickets be x

and the total amount each has be y

For Jessica

the amount is

y=10x1

for Laurie the amount is

Note: she has $360 already

y=360+6x2

to find the number of the tickets that will make them have the same amount, let us equate 1 and 2

10x=360+6x

10x-6x=360

4x=360

x=360/4

x=90

10000

step-by-step explanation: divide by 2,

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.
