The rule 2d + 3.5m = c can be used to find the total cost in dollars, c, of buying d donuts, and m muffins at a bakery. what does the rule tell you about the cost of a donut and the cost of a muffin at this bakery?

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.
