Answer:
A. 40x + 10y + 10z = $160
B. 8 Roses, 2 lilies and 2 irises
C.
1. 20x + 5y + 5z = $80
2. 4x + y + z = $16
3. 8x + 2y + 2z = $32
Step-by-step explanation:
Cost for each flower = $160/5 = $32
So we have $32 for each bouquet consisting of 12 flowers each.
Roses = x = $2.50 each
lilies = y = $4 each
irises = z = $2 each
8x + 2y + 2z = $32
8($2.50) + 2($4) + 2($2) = $32
$20 + $8 + $4 = $32
$32 = $32
a. Maximum budget is $160
40x + 10y + 10z = $160
40($2.50) + 10($4) + 10($2) = $160
$100 + $40 + $20 = $160
$160 = $160
b. From above
8x + 2y + 2z = $32
8 Roses, 2 lilies and 2 irises
c. No. There are other solutions If total cost is not limited
1. 20x + 5y + 5z
20($2.50) + 5($4) + 5($2)
$50 + $20 + $10
= $80
2. 4x + y + z
4($2.50) + $4 + $2
$10 + $4 + $2
= $16
3. 8x + 2y + 2z
8($2.50) + 2($4) + 2($2)
$20 + $8 + $4
= $32
47.93 is the answer because multiplication and addition
Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
➳This number can be written in scientific notation as 1.86 times a power of 10.
