Answer:
Before going to the bakery, Lisa had more than $32.40.
Step-by-step explanation:
Hi there!
Let x be Lisa´s savings.
She brings half of her savings to the bakery and expends $14.20. What is left is more than $2.00. Then:
x/2 - 14.2 > 2
Let´s solve the inequality:
x/2 - 14.2 > 2
Add 14.2 to both sides of the inequality.
x/2 > 2 + 14.2
x/2 > 16.2
Multiply by 2 both sides of the inequality.
x > 32.4
Before going to the bakery, Lisa had more than $32.40.
Answer:
Step-by-step explanation:
The equations are:
The two graphs intersect when:
To find the area under the curve for the first equation:
To find the area under the curve for the second equation:
To find the total area:
Simplifying the equation:
Note: The reason the area is equal to the area two minus area one is that the line, area 2, is above the region of interest (see image).
