Jarod has budgeted at most $1250 for a vacation. he has already spent $439 on airfare. write and solve an inequality to determine the amount of money left in jarrod's budget.

$439 + x ≤ $1250

x ≤ $811

Step-by-step explanation:

Since Jarod can spend at most $1250 on his vacation, that means he must spend that amount or below, so when setting up the inequality the sum of his airfare and remaining money must not be higher than $1250 or ≤ $1250.  Since the only thing Jarod has bought so far is airfare, his inequality is:

$439 + x ≤ $1250

Subtracting $439 from both sides: $439 + x - $439 ≤ $1250 - $439

Solve for 'x':  x ≤ $811

step-by-step explanation:

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
