PLEASE HELP ME IM THE WORST AT MATH (There are 4 more questions unless I find the answers. Also, giving brainliest)
Michael had $550 in his savings account. He took out $30.75 every month for one year. What is the net change in Michael’s account balance following these withdrawals?
A. -$519.25
B. -$369
C. $369
D. $519.25

The answer is -$369.00

30.75 x 12 = 369

They are taking away from his account so it would be a negative.

$550-$369 is the net change in his account balance.

hope this helps

also translate this it is French btw

j'espère que cela aide beaucoup et vous êtes les bienvenus pour la réponse

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
