You have a gift card worth $90. you wanna buy several movies that are $12 each. write and solve an inequality that represents the number of movies you can buy with at least 30 dollars on the gift card

5 Movies and 12x≤90-30

Step-by-step explanation:

So first you would want to subtract the $30 from the $90 assuming you want to save $30 (I got 60 from 90-30) then you would divide 60 by 12 giving you 5

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.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
