Answer:
i think it would be 18 dollars not entirely sure tho.
Step-by-step explanation:
if she ended with 17 and 8 of those dollars were bc of her washing her family car. u would subtract 17-8 which is 9 dollars.but she also spent half of her money before that. so u would add another 9 dollars. so ur answer would be 18 dollars.
hope this is right...
First, write an equation system based on the problem
For an instance, d stands for the number of dimes and n stands for the number of nickels. Dime's worth $0.10 and nickel's worth 0.05
"Pudge had 2.25 dimes and nickels" could be written as
⇒ 0.10d + 0.05n = 2.25 (1st equation)
"He had twice as many dimes as nickels" could be written as
⇒ d = n (2nd equation)
Second, solve the equation system
Substitute d as n from the second equation to the first equation to find the number of nickels
0.10d + 0.05n = 2.25
0.10n + 0.05n = 2.25
0.15n = 2.25
n = 2.25/0.15
n = 15
Because d = n, therefore d = 15
Pudge has 15 coins of dimes and 15 coins of nickels
