Do each equation individually and compare if they are the same end answer in each question. which ever one is unequal than that is the answer
Answer:
$8.50
Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r
$40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.
($31.50) + r
$40
r
$40 - $31.50
r
$8.50
There are 12 thousands, so we put that in the thousands place
12,000
now add it to 12 in the thousandths place
0.012
12,000.012
