Answer:
10 students would spend $30.
Step-by-step explanation:
In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.
$12/4 students = $3 per student.
Now we take that unit rate and multiply by the new number of students.
$3 * 10 students = $30 total spent.
Food A contains 150 calories in 3/4 of a serving
Food A will contain (150 x 4)/3 = 200 calories in 1 serving.
Food B contains 250 calories in 2/3 of a serving
Food B will contain (250 x 3)/2 = 375 calories in 1 serving.
Food A has fewer calories per serving.
