An $42 item was marked down by 50%<br><br> what is the new cost of the item?
Nataly_w [17]

Answer:

New Cost of item is \$ 21

Step-by-step explanation:

Given:

Original Cost of item = \$ 42

Item was marked down by 50\%

To Calculate Cost after 50\% marked  down we need to multiply original cost by 50 and then divide by hundred.

Cost after  marked down = \frac{42 \times 50}{100}= \$21

Now New cost of the item is calculated by Subtracting Cost after 50\% marked down by Original Cost of item.

New cost of the item =  \$ 42 - \$ 21 = \$21

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she
SOVA2 [1]

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

s=\dfrac{48}{b}

Hence, the required expression is (48/b).
