Write an inequality and solve the equation.
Answer to Problem 34PPS
Variable: x;
Explanation of Solution
Given:
Keisha is babysitting at $8 per hour to earn for a car. So far she has saved $1300. The car that Keisha wants to buy costs at least $5440. How much money does Keisha still need to earn to buy the car?
Concept Used:
Let the money Keisha still need be $ x
Now convert the condition given in the question into an inequality.
Keisha has saved $1300 and needs at least $5440.
Therefore she needs at least $(5440 − 1300) more or at least $4140.
At least means the sign
Inequality:
Calculation:
Inequality:
Keisha has saved $1300 and needs at least $5440.
Therefore she needs at least
Solve for x :
She needs at least $4140 to reach the minimum amount of $5440.
Solution:
Thus, Keisha still needs to earn at least $4140
