The amount of money Kylie spends on food to the amount she spends on gas per week is 7:4. She spends $45 more on food than gas. How much does she spend on food? How much does she send on gas? On one of the weeks, she spends an additional $75 on food for a dinner party. What is the ratio of the amount she spends on food to the amount she spends on gasoline for that week?
