Reflect
1 Dan stocked up on batteries.
• He bought 10 packages of AA and AAA batteries for a total of 72 batteries.
• The AA batteries are sold in packages of 6, and the AAA batteries are sold in
packages of 8.
Write a system of equations that can be solved to find how many packages of each type
of battery Dan bought. Remember to define your variables.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
