suppose yogurt is on sale for $0.50 a piece, and you have a coupon for $0.30 off your total purchase. write a function rule for the coast of n yogurts. how much would 20 yogurts cost?

a: c(n)=0.50n-0.3; $9.70
b: c(n)=0.30n-0.5; $5.50
c: c(n)=0.2n; $4.00
d: c(n)=035n; $10.00

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
