Read the passage by Peter N. Sterns. The past causes the present, and so the future. Any time we try to know why something happened . . . we have to look for factors that took shape earlier.
I WILL MARK BRAINLEST IF CORRECT HELP PLS
According to the writer, why is it important to study history?

so we can see how things change over time
so we can understand how the present came to be
so we can learn interesting facts about the past
so we do not repeat mistakes of the past

answer: yes youre right.

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
