Answer:
the price for each doughnut is $1.05
Step-by-step explanation:
doughnuts = d
cookies = c
2d + 3c = $3.30
5d + 2c = $4.95
to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.
4d + 6c = 3.30
-15d - 6c = -14.85
combine like terms
-11d = -11.55
divide by -11
d = 1.05
First 3/8, second 2/3, and third 19/24
the value of the car will be 3250 after 5 years
Step-by-step explanation:
the value of the car = 13000
rate of interest = 15%
time = 5 years
in 5 years the car will depreciates = 13000 X 15% X 5
=
= 9750
after 5 years the value of the car is = 13000 - 9750 = 3250
