Answer this: richmond high school purchased 90 graphing calculators for $118 each. the school received a manufacturer's rebate of $10 per calculator. what was the final price?

Per Calculator $118-$10=$108

Total amount $108×90=$9720

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.
