Step-by-step explanation:
x = number of novels
y = number of dictionaries
x = 8y
88x + 208y = 13680
now, using the identity of the first equation in the second equation gives us
88(8y) + 208y = 13680
704y + 208y = 13680
912y = 13680
y = 13680/912 = 15
x = 8y = 8×15 = 120
so, there were 120 novels and 15 dictionaries sold.
So the tower is going to be larger than the shadow but not to large so let work from there and not to large so the only logical answer is d
Answer:
$131.25
Step-by-step explanation:
175×0.25=43.75
175-43.75=131.25
The answer is a. $20.40
explaining: if you add 287 and 121, you’ll get 408. You can’t multiply percents so you have to change it into a decimal.
287+121=408
408x0.05= 20.40
