Question

a variable: 51 (the number of tickets moira sold) + x (the unknown number of tickets kerr sold) = 72 (the total number of tickets sold). any variable, from a to z, can be used to represent kerry’s tickets here; it doesn’t have to be x. which of these situations could be written as an equation with one variable? choose one option a penny picked 35 apples, ben picked 22 and sam picked 17. they picked 74 apples all together. who picked the most apples? b harriet and lea found 9 four - leaf clovers on the baseball field in all. harriet found 5 of them. how many clovers did leah find? c there were 45 doughnuts at the snack table today. tanisha brought 33 of them, and doug brought 12. where did tanisha buy her doughnuts? d lori bought the most t - shirts of anyone in her family. she bought 1 more t - shirt than thea and 3 more than pino. how many shirts did lori buy?

Explanation:

Step1: Analyze Option A

This asks who picked the most apples, which is a comparison question, not requiring a one-variable equation. We just compare 35, 22, 17 directly.

Step2: Analyze Option B

Let $x$ = number of clovers Leah found. The total is 9, so we write the one-variable equation: $5 + x = 9$. This fits the requirement.

Step3: Analyze Option C

This asks a location question, which has no mathematical variable or equation involved.

Step4: Analyze Option D

This has three unknowns (Lori's, Thea's, Pino's T-shirts), so it requires multiple variables, not one.

Answer:

B. Harriet and Lea found 9 four-leaf clovers on the baseball field in all. Harriet found 5 of them. How many clovers did Leah find?
