If 4a - 13 = 6b + 35 = 8c -17 = d, find the smallest possible value of a + b + c + d.(they are integers)

The smallest possible value of a+b+c+d is: 4

Step-by-step explanation:

since we are given that:

4a - 13 = 6b + 35 = 8c -17 = d

on taking the first two equality i.e. 4a-13=6b+35

we get

on using the first and third equality we have:

4a-13=8c-17

also from the first and last equality we have:

d=4a-13

Hence,

the smallest possible value such that the expression a+b+c+d is positive will be claculated as:

a+b+c+d>0

that means

But as a is an integer, hence the smallest such value is 4.

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

the correct answer is 828.07
