Answer:
A
Step-by-step explanation:
We know that length · width = area, width = w, and length = 2 * width = 2w so the answer is 2w · w = 338.
$7865 put 5 in for t times 411 is 2055 + 5810
The quick way to do this is to multiply the bill by 1, mult. it again by 0.18, and then add the two results together.
Better and faster: Mult. the bill amount ($42.75) by 1.18:
1.18($42.75) = $50.45 (answer)
Y X
80 32
100 x'
80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40
