Answer:
ans=132
Step-by-step explanation:
3 1/4 cups for 13 servings...
(3 1/4) / 13 =
13/4 * 1/13 =
13/52 which reduces to 1/4 cup per serving
for 28 servings...
1/4 * 28 = 28/4 = 7 cups <== 28 servings requires 7 cups of flour
Answer:
3.7*10⁷ people.
Step-by-step explanation:
Estimated population of California = 3.9*10⁷ people
Estimated population of Maine = 1.3*10⁶ people.
Let x represent the estimated number of people that live in California more than Maine.
The number of people that live in California more than Maine can be found by finding the difference between the population of California to Maine.
No. Of people living in California - no. Of people living in Maine = estimated no of people that live in California more than Maine.
X = 3.9*10⁷ - 1.3*10⁶
X = 3.7*10⁷ people
About 3.7*10⁷ people live more in California than Maine
