True [87]

Answer:

Step-by-step explanation:

Total amount of Money saved by Manny is $150. He wants to buy a digital player with it.

The digital music player costs $89, and each song costs $0.99. Let x represent the number of songs that he can afford. This means that the cost of x songs would be

89 + 0.99x

If Manny spends no more than $150, before tax, the number of songs that he can buy will be

89 + 0.99x = 150

0.99x = 150 - 89 = 61

x = 61/0.99 = 61.6

He can buy 61 songs

Answer:

With an ageing population, dietary approaches to promote health and independence later in life are needed. In part, this can be achieved by maintaining muscle mass and strength as people age. New evidence suggests that current dietary recommendations for protein intake may be insufficient to achieve this goal and that individuals might benefit by increasing their intake and frequency of consumption of high-quality protein. However, the environmental effects of increasing animal-protein production are a concern, and alternative, more sustainable protein sources should be considered. Protein is known to be more satiating than other macronutrients, and it is unclear whether diets high in plant proteins affect the appetite of older adults as they should be recommended for individuals at risk of malnutrition. The review considers the protein needs of an ageing population (>40 years old), sustainable protein sources, appetite-related implications of diets high in plant proteins, and related areas for future research.
