Answer:
T = 75 + 116.9*N
Step-by-step explanation:
We have that the equation for Michael's savings is:
A = 75 + 50.85*N, where N is the number of weeks
And we have that the equation for his wife's savings is:
B = 65.95*N.
So, to find the total amount saved using both plans combined (T), we have to sum A and B:
T = A + B = 75 + 50.85*N + 65.95*N = 75 + 116.9*N
So the equation that relates T to N is:
T = 75 + 116.9*N
Answer:
Step-by-step explanation:
Step one: because fractions are out of 100% you do
5%+100%= 105
105 divide by 100 which is equal to 1.05
Step two: it’s says two year so what you do is times the amount by the number you got
75x

For #7 - part a: greatest common factor (GCF) is 5.
Part b: cross out everything BUT 10 & 20.
We just need to extrapolate the information we have about 25 apples to 100, that is we need to find a number that multiplied by gives us 100, from this original fraction, hence, we have:
2 out of 25 = 2/25
if we multiply and divide a number or fraction by the same number we do not alter its value, so we need to convert the 25 into 100, and that can be done multiplying it by 4, like so:
(2/25)(4/4) = (2*4)/(25*4) = 8/100
So if we have 2 bruised apples out of 25, then we can expect to have 8 bruised apples out of 100
