Answer:
Ashley= 15
Milan= 11
Carlos= 105
Step-by-step explanation:
Let, A, M and C denotes Ashley, Milan and Carlos respectively.
A+M+C= 131 (according to the question)
Here,
C= 7A
A= M+ 4
So, M= A - 4
Now,
A+M+C = 131
or, A+ A-4+ 7A = 131 (putting the values)
or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)
or, 9A = 131 + 4
or, 9A = 135
or, A = 135 / 9
So, A = 15
C= 7A = 7×15= 105
M= A-4 = 15 - 4 = 11
Answer:
$106.3
Step-by-step explanation:
$3200 = Know (goal / need)
$1500 = Given
3200 - 1500 = 1700 = what's left
160.3 × 16 = 1700.8
↑(the closest you can get to 1700)
so they will need to save $106.3 a week to get 3200
