You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.
You just need to divide both sides by 0.25:
Now the left hand side simplifies:
Answer:
I'm pretty sure it's 195 times
Step-by-step explanation:
(3, 23, 30-39 (extra for 33), 43, 53, 63, 73, 83, 93) x 5 = 95
95 + 100 (from 300's) = 195
