The rate of the increase to the nearest percent is 30 percent
Answer:
$3,500 at 10% and $6,500 at 7%.
Step-by-step explanation:
M * 10% + (10000 - M) * 7% = 805
0.1M + 700 - 0.07M = 805
0.03M = 105
M = 3500
Answer:
Anjali can buy 4 bulbs of jumbo garlic if she has $3.96.
Step-by-step explanation:
To calculate how many bulbs of jumbo garlic Anjali can buy with $3.96, we must first calculate the unit rate of the jumbo garlic. Julio buying 12 bulbs of jumbo garlic for $11.88 can be represented as:

Divide the fraction by
to calculate the unit rate:

So if each bulb of garlic costs $0.99, which we can think of as being $1.00 at the moment, we could figure that Anjali's $3.96 would be closer to $4 than it is to $3, so let's multiply the unit rate by
:
× 

Therefore, Anjali can buy 4 bulbs of jumbo garlic if she has $3.96.

Check your work by dividing
by
to see if you will get your initial unit rate:
÷ 

Therefore, our solution is correct!
Answer:
210 by 120
Step-by-step explanation:
perimeter=2l+2w
length= 2w-30
width= w
2(2w-30+w) = 660
6w-60= 660
6w= 720
w=120
length= 2*120-30 = 210
