Let
x---------> <span>The probability that a student takes Spanish
y-------> </span><span>the probability that a student takes Drivers Education given that the Student is taking Spanish
z-------> </span><span>The probability that a student at school takes Drivers Education and Spanish
we know that
z=x*y------> solve for y
y=z/x
z=87/1000
x=68/100
substitute
y=(87/1000)/(68/100)-----------> y=87/680
the answer is
87/680</span>
Answer:
Step-by-step explanation:
Mp=$1200
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180

Answer:
310 cones sold
Step-by-step explanation:
Out of the 3:5:2 ratio, the 155 chocolate represents the 5 in there
We should find the value of "1" by dividing 155 by 5
155 divided by 5 is 31
Now we know the base value is 31, keep this in mind because we will need it later
Since we are trying to find the total number of cones sold, we should add all the ratio numbers together
3+5+2=10
Now that we know the total is "10", we just have to multiply 31 by 10
31x10=310
310 cones sold
