Great Job! they are all correct. :)
Good luck in your next tests.
If the ratio of miles is
.. mr : mrs = 3 : 1
The total number of "ratio units" is 3+1 = 4, so each one stands for 3200/4 = 800 miles.
Mr Storey drove 3*800 = 2400 miles
Mrs Storey drove 1*800 = 800 miles
Answer: x+y =12
0.40x+0.50y =5.70
Step-by-step explanation:
Let x = Number of ears of yellow corn
y - Number of ears of peaches and cream variety.
AS per given,
x+y = 1 dozen
⇒ x+y =12 [1 dozen =12]
Cost per ear of yellow corn = 40 cents = $0.40 [1 dollar = 100 cents, 1 cent = 0.01 dollar]
Cost per ear of peaches and cream variety = 50 cents = $ 0.50
Total cost ( in$): 0.40x+0.50y =5.70
Required system of equations represents the number of ears of corn of each type that Larji purchased:
x+y =12
0.40x+0.50y =5.70
