Students from four classes are in talent show.

Mathematics
1 answer:
KIM [24]3 years ago
5 0

Answer:

A. 8 students

B. Because 24% of 24 is 5.76

Step-by-step explanation:

A:  The ratio of students is 2:5, that means for every 7 students from her class, 2 of them are in the show.  

   28/7 is 4, so there are 2(4) = 8 students in the talent show.

B:  24(24%) = 24(0.24) = 5.76.  The question says 'exactly' 24%.  We can't have 0.76 of a person, so we can't have 'exactly' 24%

JA mattress store in Stafford purchased a mattress at a cost of $255 and marked it up 100%. Later on, Cassie bought the mattress
goldenfox [79]

Answer:

She pays $566.10

Step-by-step explanation:

The mattress store marks a mattress up 100%. 100% of $225 is 225. We add 225 to 225 and get 510. Therefore, the store sells the mattress for $510 without tax. When Cassie buys the mattress, we have to add 11% tax. We change 11% to 0.11 and multiply that by the selling price (510). We get 56.10, so that is the tax. We add the tax to the selling price and get $566.10. Cassie pays $566.10 for the mattress.

I hope this helped and please mark me as brainliest!
