Question

If the total bill at a restaurant, including a 15% tip, is
$65.32, what was the cost of the meal alone?

Answer 1

let the cost of meal alone be C
65.32=total cost +15%
hence
C + 0.15*C = 65.32
1.15*C=65.32
C=56.80

when C is added to equation
you get
56.80+1.15=65.32

Answer 2

make it into an equation, where the cost of the meal alone was C:

C + 0.15*C = 65.32
1.15*C=65.32
C=56.80

if you look at the second line, you can see that 65.32 is 115% of the cost. 100% plus 15%. Remembering this can help you solve these more quickly in the future.

Answer 3

X is the cost of the meal
.15x is 15% of the meal.

x + .15x = $65.32
1.15x=$65.32
x = $65.32 / 1.15
x = $56.80

Answer 4

x = cost of meal
.15 x =tip
1.15x = 65.32
x= 65.32/1.15 = $56.80

Answer 5

Yes you can label the variable x as width and length can be x + 12 make an equation 2x + 2(x+12) = 156 because you add all sides to get perimeter then u solve for x yielding the answer x = 33 = width x + 12 = 45 = length

Answer 6

.15 * 65.32 = 9.798

65.32 - 9.798 = 55.522 = 55.52

$55.52

Answer 7

that doesn't work if you reverse it

what you need to solve for is this
total cost = meal cost + meal cost(tip%)

y = x + xz
y = x + .15x
y = x(1 + .15)
y/(1.15) = x

65.32/1.15 = x
x = 56.8
56.8 * 15% = 65.32

Answer 8

(65.32(100))/115
= 6532/115
= $56.80

Answer 9

$56.80 cents it the cost of the meal. Tip is 15% which for that meal is $8.52.

Answer 10

65.32/1.15=56.80
