Answer 1

Answer:

276 miles, $ 20.148

Step-by-step explanation:

Given:

Donald Duck's car travels in 1 gallon gas = 30 miles

Cost of 1 gallon = $ 2.19

Question asked:

Distance travel in 9.2 gallons = ?

Cost of 9.2 gallons of gas = ?

Solution:

By applying unitary method:

His car travels in 1 gallon = 30 miles

His car will travel in 9.2 gallons = $9.2\times30$

                                                    =  276 miles

Cost of 1 gallon = $ 2.19

Cost of 9.2 gallons = $9.2\times2.19$

                                = $ 20.148
