Step-by-step explanation:
The closed to the answer is C
Let Edy's money be x.
Lucy: 35% more --- (135/100) x
x + (135/100) x = 206.80
(47/20)x = 206.80
47x = 206.8 x 20
47x =4136
x = 88
Edy saved $88.
Lucy saved (135/100)(88) = $118.80
Answer:
(2.5,10.5)
Step-by-step explanation:
In the abscissa (x), A is in the middle point between 0 and 5:
In the ordinate (y), A is in the middle point between 9 and 12:
Then, the coordinates of point A are:
A=(x,y)→A=(2.5,10.5)
Answer:
D(t) = 2,280 - 60t
for D(15) compare the eqns and substitute the value of t.
D(15) = 2,280 - 60(15)
D(15) = 1,380 miles.
In the context of the qn, the Chang family travels 1,380 miles in 15 hours.
