Question

The Morrison family budgeted 20% of their disposable annual income of $40,000 for food, but found they needed $40 more per week. What percent of their income shouldnow be budgeted for food (to the nearest tenth of a percent)?23.8%24.6%25.2%26.9%None of these choices are correct.

Answer 1

$40000\cdot0.20=8000$

$40 more per week in one year (52 weeks per year) is

$40\cdot52=2080$

The sum of the previuos budget and this new amount is

$8000+2080=10080$

To know the ratio against the annual income, we do this:

$\frac{10080}{40000}\cdot100=0.252\cdot100=25.2$

The answer is 25.2%
