My opinion is d/1 okay and i did not understand
The only step that arena make wrong is step number 2
40 x 0.08875 = 3.55
40 + 3.55 = 43.55
the sum is $43.55
Answer is C) 51
Angle y is 62 degrees because it forms a straight line with the angles next to it (57 and 61) so angle y must be 62.
There are 180 degrees in a triangle so 180-62-67 = 51
Let's say the savings in your account are given by $V, the number of weeks by n and the starting balance by $x:
V = x + 200n
Now if after saving for 4 weeks you have $1700 in your account, then:
1700 = x + 200*4
1700 = x + 800
x = 900, thus your starting balance is $900
Using this information we can now write up the general equation for the savings at the end of each week:
V = 900 + 200n
