Mr. berriman bought 8 packages of dry erase markers m and 4 whiteboard erasers w for $72. mr. williams bought 12 of the same packages of dry erase markers m and 2 of the same whiteboard erasers w for $98. based on this information, what is the cost of one package of dry erase markers?
a. $2.50
b. $7.75
c. $7.25
d. $7.50

E=eraser pr m=marker pr 4e+8m=72 2e+12m=98 solving you'll get m=7.75 e=2.5 answer is B

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
