Kelly spends $63.90 on items for a party. she buys you cards that cost $5.40 (including tax). she also buys gift bags that cost $11.70 each. if she buys one gift bag for each guest, how many guests did kelly invite to the party?
a.
6
b.
5
c.
8
d.
4

$63.90 (total)

$5.40 (cards)

$11.70/per (bags)

$63.90 - $5.40 = $58.50

$58.50 / $11.70 = 5

She invited 5 guests (b).

Ok, so 2 solutions, 1 is if buy cards for every guest
other is if buy only 1 gift card

1st one

63.9=5.4x+11.7x
63.9=17.1x
divide both sides by 17.1
crazydecimal=x
wrong, yo can't buy a decimal amount of cads

2nd
63.9=5.4+11.7x
minus 5.4 both sides
59.5=11.7x
divide both sides by 11.7
5=x

5 guests

B is answer

It will be a whole number.
