#### Answer

Lerae’s plan permits 1200 calories

#### Work Step by Step

Let X represent the amount of calories that are permitted by Lerae’s plan.
Twice the number of calories permitted by Lerae’s diet plan means 2X.
650 calories less than twice the number of calories permitted by Lerae’s diet plan means 2X - 650
Todd is following a 1750-calorie-per-day diet plan.
So, we obtain:
2X - 650 = 1750
Add 650 to both sides
2X = 2400
Divide both sides by 2
X = 1200
