Adepartment store buys 300 shirts at a cost of 1800 and sells them for $10 each. find the percent markup rounded to the nearest percent

67%

Step-by-step explanation:

Given : A department store buys 300 shirts at a cost of $1800 .

Then By unitary method , the cost of one shirt = Cost of 300 shirts divided by 300

= $1800 ÷ 300 = $6

i.e. cost of one shirt = $6

Also, Selling price of one shirt = $10

Price mark up = Selling price - Cost price

= $10-$6 = $4

The  percent mark up=

(rounded to the nearest percent)

Hence, the percent markup = 67%

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
