Gabby's Christmas budget is $1800. She gives 16 also, the weird numbers are fractions by the way so, ya 1
6
of her budget to charity. Of her remaining budget she spends 15
1
5
on decorations. How much money does she have left in her budget for Christmas presents? And the answer is not 1756

the answer is 2/54

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
