Question

Answer 1

33.3%

Explanation:

Cost of breakfast = $1.25

Cost of breakfast = $3.75

We have to calculate what percent of the cost of lunch is the cost of breakfast. This can be done by dividing the cost of breakfast by cost of lunch and multiplying the result by 100% as shown below:

`\frac{\textrm{Cost of Breakfast}}{\textrm{Cost of lunch}} * 100 \%\\\\= (1.25)/(3.75) * 100 \%\\\\=(1)/(3) * 100 \%\\\\=33.3\%`

Thus cost of breakfast is 33.3% the cost of lunch.
