Answer:
Option D. 1.29x + 1.35y ≤ 12
Step-by-step explanation:
Nick is making a fruit salad.
He buys apples per pound for = $1.29
He buys oranges per pound for = $1.35
He spend no more than $12.00 or we can say less than equal to $12
Let x represent the number of pounds of apples that Nick buys and y represent the number of pounds of oranges.
Cost of x pounds of apples = $1.29x
Cost of y pounds of oranges = $1.35y
Total cost = 1.29x + 1.35y
Total cost should be less than equal to $12.00
Therefore, inequality will be 1.29x + 1.35y ≤ 12
Option D. is the answer.
Answer:
It is 39 cupcakes.
Since he charges $2 per cupcake (39), it is 78.
He makes profit so subtract 30 from 78 and you get $48.
Answer:
10
Step-by-step explanation:
Do 40+8 first which is 48. then you think "what times four is 48" which is 12. so you need to add something to 2 to make 12. which is 10. A=10 :)
First, we determine the area of the wall before cutting out the door by multiplying the dimensions given.
area of wall = ( 9 ft)(5.25 ft) = 47.25 ft²
Then, we determine the area of the door by subtracting from the total area the area of the remaining wall.
area of door = 47.25 ft² - 26.25 ft² = 21 ft²
The two whole numbers that can be the sides of the door are 7 ft x 3 ft.
