30% = 0.3.
0.3*80 = 24, so we know that 30% of 80 is 24.
80 - 24 = 56, so after the sale, the price for a pair of jeans is $56.
10% = 0.1
0.1*56 = 5.6, so with the coupon, we get $5.60 off.
56 - 5.60 = 50.40
The jeans cost $50.40 after the sale and the coupon.
Hey there!
2/3 = a/30
First: you have to CROSS MULTIPLY the given numbers
2(30) = 3(a)
2(30) = 60
3(a) = 3a
New EQUATION: 3a = 60
Second: DIVIDE 3 to BOTH SIDES
3a/3 = 60/3
CANCEL out: 3/3 because that gives you 1
KEEP: 60/3 because that helps you solve for your a-value
60/3 = a
60/3 = 20
Therefore, your answer is: a = 20
Good luck on your assignment and enjoy your day!
