The first thing we must do for this case is find the number of total guitarists.
We have then:
We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.
We have then:
Where,
x: number of guitarists playing jazz alone
From here, we clear the value of x.
Then, the number of guitarists who play classical solo is:
Answer:
30 guitarists play classical solos in the contest

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!
Step-by-step explanation:
( y = 4x/5 + 2)
m1.m2 = -1
4/5.m2 = -1
m2 = -5/4
formula = y - y1 = m2 ( x - x1)
y - 3 = -5/4 ( x - 6)
y -3 = -5x /4 + 30/4
y = -5x /4 + 21/2
