So the larger number is x, and the smaller number is y
7y=x
3x=7+4y
(So plug in the 7y=x information into the second equation)
3(7y)=7+4y
21y=7+4y
17y=7
y=7/17
3/5 equals to 0.6 so it's less than 4.9
C,g,a,j my teacher graded it with me today hope this helps! :)))
Part B
Divide 63 by 3 to get 21, the price of one shirt.
Divide 21 by 7 to get 3, 10% of the original price.
Multiply 3 by 10 to get 30, the original price of one shirt.
Answer: $30
Part C
Divide 40 by 10 to get 4, 10% of original price
Multiply 4 by 3 to get 12, 30% of the original price
subtract 12 from 40 to get 28, the price after discount
Divide 28 by 10 to get 2.8, the second 10% discount.
Subtract 2.8 from 28 to get 25.2, the final price.
Answer: $25.20
