A $22,000 car depreciates by 12% per year.

1 answer:

5 0

$22,000 * 0.12 = $2,640
so
$22,000 - $2,640 = $19,360
so
$19,360 after 1 year.

$19,360 * 0.12 = $2,323.20
$19,360 - $2,323.20 = $17,036.80 (2 years)

$17,036.80 * 0.12 = $2,044.416
Don't round until you finish the problem.
$17,036.80 - $2.044.416 = $14,992.384 (3 years)

$14,992.384 * 0.12 = $1,799.08608
$14,992.384 - $1,799.08608 = $13,193.29792 (4 years)
ROUND
$13,193.29792 rounded to $13,193.30

A local hamburger shop sold a total of 712 burgers on Tuesday

There are 62 more cheeseburgers than hamburgers

let cheeseburers = c
let hamburgers = h

h + 62 = c
c + h = 712

Plug in h + 62 for c

(h + 62) + h = 712
2h + 62 = 712
2h + 62 (-62) = 712 (-62)
2h = 650
2h/2 = 650/2
h = 325

There are 325 hamburgers sold on Tuesday

c = 325 + 62
c = 387

<em>There are 387 chesseburgers sold on tuesday </em>(in case you were wondering)

hope this helps
