The answer is 35.2 because you just have to add them
Answer:
any value less than or equal to 10
Step-by-step explanation:
'up to' means do not exceed
It is $100 since you are rounding to the nearest ten.
Total = Principal * (1 + rate)^years
Total = 1,100 * (1.08)^15
Total = 3,489.39
1. Turn units into variables---> S= Salads, L=Lemonade
2. Set up two equations using the variables and information give.---> 3S + 2L= $14 and 2S + 4L = $12.
3. Set the equations up like this;
(3S+2L=14)
(2S+4L=12)
4. Use elimination. To use elimination you need to pick one variable and make the variables cancel. For the variable to cancel one has to be negative and one has to be positive.
5. This is what I mean;
(3S+2L=14) * -2 = (-6S-4L=-28)
(2S+4L=12) * 3 = (6S+12L=36)
6. Now add the variables together;
-6S+6S=0
-4L+12L= 8L
-28+36= 8
7. Rewrite with what is left and solve;
8L=8
L=1
8. Plus in L to one of the two original equations and find S;
3S+2(1)=14
3S+2=14
3S=14
S=4
9. Write out your answer---> The Salads cost $4 each and the lemonade costs $1 each.
