Ninth grade class at be high is having a fundraiser they need to raise at least $1,500 they are selling magazines for $7 each how many subscribers subscriptions does that class need to sell to meet their fundraising goal

The class will need to sell a minimum of 215 subscriptions at $7 each to reach their goal of $1500.  

Step-by-step explanation:

You can solve this problem by setting up an inequality, with a variable, to find the number of subscriptions needed to reach their goal of $1500.  Since the goal is to raise at least $1500, our expression must be ≥ 1500.  Let 's' be the number of subscriptions:  7s ≥ 1500.  Then, use inverse operations to isolate the variable, so divide both sides by 7:  7s/7 ≥ 1500/7 or s ≥ 214.3.  Since they can't sell a partial subscription, we would need to round up to 215 total subscriptions that they would need to sell to meet their fundraising goal.  

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
