An item is regularly priced at $85. Keith bought it at a discount of 65% off the regular price.
how much did Keith pay?
To find how much Keith paid, we need to calculate 65% of $85 and then subtract that amount from the regular price.
The discount amount is 65% of $85:
Discount = 65/100 * 85
Discount = $55.25
Keith paid the regular price minus the discount:
$85 - $55.25 = $29.75
So, Keith paid $29.75.
The price of an item has been reduced by 70%. The original price was $34.
what is the price of the item now?
To find the price of the item after the reduction, we need to calculate the 70% of the original price and then subtract that amount from the original price.
The reduction amount is 70% of $34:
Reduction = 70/100 * 34
Reduction = $23.80
The price of the item now is the original price minus the reduction:
$34 - $23.80 = $10.20
So, the price of the item now is $10.20.
An item is regularly priced at 17$. Lisa bought it on sale for 95% off the regular price.
How much did Lisa pay?
To find out how much Lisa paid, we need to calculate 95% of $17 and then subtract that amount from the regular price.
The discount amount is 95% of $17:
Discount = 95/100 * $17
Discount = $16.15
Lisa paid the regular price minus the discount:
$17 - $16.15 = $0.85
So, Lisa paid $0.85.
Simplify
3c-9c
To simplify the expression 3c - 9c, we combine like terms.
The coefficients of c are 3 and -9, so when we subtract 9c from 3c, we get:
3c - 9c = -6c
So, the simplified expression is -6c.
Simplify
-11u + 3 + 11u
To simplify the given expression, we combine like terms.
The terms with "u" are -11u and 11u. When we add -11u and 11u, they cancel each other out:
-11u + 11u = 0
Therefore, the expression simplifies to just the constant term:
3
So, the simplified expression is 3.
