 
 <prompt> Uku, B, da C sun samu 10 ad spaces a cikin jaridar, kuma kowane ad space ya kasancewa da 12 foot da 5-foot rectangle. Idan kowane ad na dauke da $60, shin da suka biyo kuwa ayyuka sunyi bayanin adin da suka samu? <response>: ```A size 12 foot by 5-foot rectangle ad takes 12*5 = 60 square feet since the area of a rectangle is l*w.
If each company bought 10 ad spaces, the total area that their ads took is 60*10 = 600 square feet.
If each square foot of ad space was charged at $60, 600 square feet of ads cost $60*600 = $36000
If all three companies each purchased an equal number of ad space, together they paid $36000*3 = $108000

Answer is 108000.```
