the amusement park charges a fee of $7.50 and $0.75 for every ride. the carnival charges a fee of $10.00 and$0.50 per ride. when

andrew11 [14]

A equation to represent this situation is:

$0.75x+7.50=0.50x+10.00$

Now we have to find x.

Step 1: Subtract 0.5x from both sides.

0.75x+7.5−0.5x=0.5x+10−0.5x0.25x+7.5=10

Step 2: Subtract 7.5 from both sides.

0.25x+7.5−7.5=10−7.50.25x=2.5

Step 3: Divide both sides by 0.25.

0.25x/0.25=2.5/0.25

Answer:

x=10
They will cost the same after 10 rides.

A hungry elf ate 35 of your muffins. That was 710 of all of them! With how many did you start?

KengaRu [80]

Answer:

2094.5 muffins

Step-by-step explanation:

The problem is a little bit messy, but i’m guessing you meant that the elf ate 35% of the muffins, which 35% is 710 muffins. so since 35% of muffins is 710 muffins, let’s multiply that by 2 so we can get 70%.

so 710 x 2 is 1420. so 70% of the muffins is 1420 muffins! sadly that’s not all of the muffins. we’re still missing another 30%. since we don’t know how many muffins are in 30%, let’s just take 710 muffins - 5%. when you do that you get 674.5. so now that we know how much is in 30%, let’s take 1420 + 674.5. when you do that you get 2094.5! so you started off with 2094 and a half muffins!

If x varies inversely as y and x = 24 when y = 4, find x when y = 12.
