Solve the following three variable word problem
"Cindy sells beaded necklaces. She has three types, type A, B and C. Cindy has a total of 30
necklaces that she plans on selling. Necklace A she sells for $10 while B and C are sold for
$12 and $15 respectively. If she sells all her necklaces at these prices, she will make $395.
The sum of the number of necklaces for A and B is equivalent to the number of necklaces she
has for C. Find how many necklaces she has of each type?
O
A=10, B=5 and C=15
O
A=8, B=8 and C=14
O
A=5, B=10 and C=15
© A=10, B=10, C=10

A=5, B=10 and C=15

Step-by-step explanation:

-We are given that:

-Also, given that:

From equation i, we have that:

#we substitute A=15-B in equation ii to solve for B:

Hence, the values of our unknowns are A=5, B=10 and C=15

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

40% off the regular price is the correct answer.
