Answer:Red price hast he least least cost per gram of apple.

Step-by-step explanation:

1) considering Royal Gala, 75 gram apple cost $0.41

The cost per gram is 0.41/75 = $0.0055

2) considering Honey crisp, 93 gram apple cost $0.82

The cost per gram is 0.82/93 = $0.0088

3) considering Red Prince, 81 gram apple cost $0.36

The cost per gram is 0.36/81 = $0.0044

Since $0.0044 per gram is the lowest of the three, then the type of apple with the least cost per gram is Red prince.

Tom put 18 gallons of mid grade gas in his truck and filled up his empty five gallon gas tank with regular gas for his lawn mowe
LuckyWell [14K]

Answer:

Mid grade gas per gallon = $2.67

Regular gas per gallon = $2.37

Step-by-step explanation:

Let, x= mid grade gas, y=regular gas.

So, for 18 gallons of mid grade gas and 5 gallon of regular gas at $59.91, it can be expressed as,

18x+5y=59.91  ------------------(equation 1)

for 14 gallon of mid grade gas and 1 gallon of regular gas at 39.75, it can be expressed as,

14x+y=39.75  -------------------(equation 2)

y=39.75-14x  -------------------(equation 3)

Now substituting the value of y from (equation 3) in (equation 1) we get,

18x+5y=59.91

18x+5(39.75-14x)=59.91

18x+198.75-70x=59.91

52x=198.75-59.91

52x=138.84

x=\frac{138.84}{52}

x=2.67  -------------------------(equation 4)

Now substituting value of x from (equation 4) in (equation 3) we get,

y=39.75-14x

y=39.75-(14\times2.67)

y=39.75-37.38

y=2.37

Therefore price per gallon of mid grade gas is x = $2.67, and price per gallon of regular gas y = $2.37.
