Your class hopes to collect at least 325 cans of food for the annual food drive. there were 135 cans donated the first week and 89 more the second week.
a. write an inequality that describes this situation. let c represent the number of cans of food that must be collected by the end of the third week for your class to meet or surpass its goal.
b. how many cans are needed to meet or surpass the goal?
can someone me figure out how to do this?

a) 135+89+C ≥ 325

b) C ≥ 101

Step-by-step explanation:

Given :

Class hopes to collect at least 325 cans of food for the annual food drive.

There were 135 cans donated in the first week

89 in the second week.

C represent the number of cans of food that must be collected by the end of the third week for your class to meet its goal

Solution :

a) first week = 135 cans

  second week = 89 cans

  third week  C cans must be collected

total cans should be atleast 325

So, inequality becomes : 135+89+C ≥ 325

b)

cans are needed to meet or surpass the goal C

⇒135+89+C ≥ 325

⇒C ≥ 325- 224

⇒C ≥ 101

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
