The answer is 4 for this problem.
Answer:
The number of packages of gift wrap and greeting cards sold is 181 and 44 respectively
Step-by-step explanation:
The computation of the number of packages of gift wrap and greeting cards sold is as follows:
Let us assume the number of packages of gift wrap be x
And, for greeting cards be y
The equation are as follows
x + y = 225 ..................(1)
We can write as
y = 225 - x
4x + 10y = $1,164 ............(2)
Now put the y value in the equation 2
4x + 10 (225 - x) = $1,164
4x + $2,250 - 10x = $1,164
-6x = $1,164 - $2,250
-6x = -$1,086
x = 181
And, y = 225 - 181
= 44
Answer: 30 feet
Explanation:
Draw a vertical number line.
Mark +20 or simply 20 which is the starting position at the diving board. The value 0 on the number line is the water's surface. The position -10 is the portion 10 feet at the bottom of the pool.
Going from 20 to 0 is 20 feet. Then going from 0 to -10 is another 10 feet.
Overall, you travel 20+10 = 30 feet.
