Tonya bought a sweater that costs $29.99 plus $ 1.60 tax. She used a coupon for $10 off. She paid the cashier $25. How much change should tonya receive?

$3.41

Step-by-step explanation:

First, we can find how much Tonya needs to pay.

29.99+1.6=31.59

Next, let's find the price with the coupon.

31.59-10=21.59

Now we find the difference between what she paid, and the amount she needed to pay.

25-21.59=3.41

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.
