What's up? answer is $4.05
explained:
10% of $45 would be $4.50
4.50x4= 18
45-18= 27
10% of 27 is $2.70 half of $2.70 is $1.35
$2.70 + $1.35 = $4.05
you spent $4.05 on the snack
Answer:
$4.05
Step-by-step explanation:
40% of $45 =
(45 x 40)/100
= $18
Remaining money after spending on a hat
= $45 - $18 = $27.
15% of $27 spent on a snack
= (27 x 15) / 100 = $4.05
so
$4.05 was spent on the snack

i don’t know for sure but i just figured it out....
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!
