Kamal bought 7 packs of paper clips for a project. Then he bought 8 more packs. There are 25 paper clips in each pack. How many paper clips did he buy?

Answers

To figure how many paper clips he bought, we have to multiply the total number of packs by the number of paper clips in each pack

Total number of packs = 7+8=15
Paper clips in each pack = 25

Now multiply them
15*25=375

ANSWER:
He bought 375 paper clips

jerry receives a 15% employee discount at the store where he works. if he pays $219.30 for an item, what was the original price of the item?

Answers

Given:
Employee discount 15%.
Amount paid by employee - $219.30

If the discount is 15%, then the amount paid by the employee is only 85% of the original price. Therefore, to get the original price, we do this computation.

Original price = amount paid by employee ÷ (100%-employee discount)

O.P = $219.30 ÷ (100% - 15%)
O.P = $219.30 ÷ 85%
Original Price = $258

Discount : $258 * 15% = $38.70

Amount paid by employee : $258 - 38.70 = 219.30

Here's the math to solve it:
Original price = $219.30 ÷ (100% - 15%)
Original price = $219.30 ÷ 85%
Original Price = $258

Discount: $258 x 15% = $38.70

Amount paid by employee: $258 - 38.70 = 219.30

Hope this helps!
