Write the following word problems as a numerical expressions, and calculate the solutions using fraction operations. Present each final answer as a sentence - in the context of the question. (a) Gina spends 3/10 of her weekly income on rent, 1/5 on travel to & from university, and 1/8 on food. What fraction of her weekly income does she spend in total? (b) Use fraction operations to show that, at the end of each week, 3/8 of Gina's income remains left over. (c) Gina's weekly income is $520, calculate the dollars-amount of her income that remains left over each week. (d) Gina wants to save money for a holiday at the end of the year. She calculates that her holiday will cost her $2200, but she has only 14 weeks of work until then. Gina will also have spending money - but only if her savings exceed the holiday cost. Assuming that she manages to save all of her remaining income every week, how much spending money (if any) will Gina have?
