Answer:
1092
Step-by-step explanation:
first calculate expense for each week;
25+30+40= 95
expense after saving
25-7= 18
30-7=23
40-7=33
18+23+33= 74
total saving for each week= 95-74=21
(you can also just do 7*3=21 to know total saving each week)
weeks in a year=
365 days/7= 52.14 = 52 weeks
total savings for the year= 52*21=$1092
Lani's dog weighs
pounds.
Step-by-step explanation:
Given,
Weight of Shamika's dog = ![12\frac{1}{2} = \frac{25}{2}\ pounds](https://tex.z-dn.net/?f=12%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Cfrac%7B25%7D%7B2%7D%5C%20pounds)
Weight of Lani's dog = 2/3 of Shamika's dog
Weight of Lani's dog = ![\frac{2}{3}*\frac{25}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%2A%5Cfrac%7B25%7D%7B2%7D)
Weight of Lani's dog = ![\frac{25}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B3%7D)
Weight of Lani's dog = ![7\frac{4}{3}](https://tex.z-dn.net/?f=7%5Cfrac%7B4%7D%7B3%7D)
Lani's dog weighs
pounds.

Answer:
See explanations below
Step-by-step explanation:
Let the amount of nickel be x
Let the amount of pennies be y
Let the amount of quarters be z
If the the total value of the coins is 3.88, then;
x+y+z = 3.88 .... 1
If Anita has 4 more nickels than pennies, then;
x = y + 4 ... 2
If she has 2 more than 4 times the number of quarters than pennies, then;
y = 2 + 4z
4z = y-2
z = (y-2)/4 ...3
Substitute 2 and 3 into 1
y+4+y+(y-2)/4 = 3.88
4y+16+4y + y-2 = 15.52
9y + 14 = 15.52
9y = 15.52 - 14
9y = 1.52
y = 1.52/9
y = 0.17
Since x = y + 4
x = 0.17+4
x = 4.17
z = y-2/4
z = 0.17-2/4
z = -1.83/4
z = - 0.46
