(5 x 10,000) + (8 x 100) + (9 x 10) + (7 x 1)

fifty thousand, eight hundred ninety-seven

Step-by-step explanation:50,897 is in standard form.

Expanded form is adding all your place values which is 50,000+800+90+7. There was a 0 in the thousand place so you do not add anything for that place value.

So (5×10,000) + (8×100) +(9×10)+(7×1) which is each number times it place value then add them all up.

Written form would be fifty thousand, eight hundred and ninety seven. So your answer is A, B, D

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

you never say the total so we cant find the percentage used for petrol
