2108 is the answer. Try to solve it on paper. It’s not hard
8 * 9 = (5 + y) * 9
multiply 8 and 9
72 = (5 + y) * 9
use the distributive property
72 = 45 + 9y
subtract 45 from both sides
27 = 9y
divide both sides by 9 to isolate the variable
y = 3
Answer:
Number of questions constraint:
x + y ≥ 15
Time constraint :
5x + 8y ≤ 120
Step-by-step explanation:
Let :
x = number of equations
y = number of word problems
Number of answers required = atleast 15
Equation takes 5 minutes
Word problem takes 8 minutes
Time available to complete exam = 120 minutes
Constraints :
Number of questions required
Total questions shout be atleast 15
x + y ≥ 15
Time constraint :
5x + 8y ≤ 120
To figure out the unit price of the hat, you would divide 259.2 by 12 to get the unit price of 21.6. Then you would multiply that number by two to get 43.20 for the total amount it would be to get the two couches hats
