Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
ok so it would round down to 42000 because the number before the 2 would have to be bigger than 5 so in this case it would round down because of the numbers value...........i hope that helped
Since they use 20.5 gallons in 492 miles you need to divide 492/20.5 which gives you 24
