How does Jake record his costs and earnings? Choose the integers to complete the statement

Jake wrote down ? for the money he spent on ingredients and ?

for the money he earned from selling the muffins.

125-16=109

Step-by-step explanation:

he earned 109 dollars bc he spent 16 and earned 125

step-by-step explanation:

abc

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.
