A dress listed from $119 is discounted 25%. What is the sale price of the dress including a 7 1/2 state sales tax?
Daniel [21]
If it is discounted 25%, then u r actually paying 75%

0.75(119) = 89.25 (without tax)

sales tax = 7 1/2% = 7.5% = 0.075
89.25(1.075) = $ 95.94 <===

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!
