Your school band needs to buy new recording equipment. The equipment will cost $3000. The band has collected $1200 in previous fundraisers. If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds?

360

Step-by-step explanation:

Total amount needed = $3000

Amount available = $1200

Remaining amount = Total amount needed - Amount available

= $3000 - $1200

= $1800

If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds

Number of sandwiches to sell = Amount remaining / price of sandwiches

= $1800 / $5

= 360

Therefore, the band will need to sell 360 sandwiches to raise remaining funds

Step-by-step explanation:

The sum of two number is 40 would be:

The second number is 5 less than twice the first number would be:

Now, we can find the value by solving this system of equations, we will isolate x in the first equation, then we replace it in the second equation:

Then, we replace this value in one equation of find the other variable:

Therefore, the value of the first number is 15 and the second number is 25.
