Step-by-step explanation:
Answer:
Ted is 6 years old
Leon is 7 years old
Andrew is 8 years old
Step-by-step explanation:
Ted+Leon=13 ⇒T+L=13 ⇒L=13-T
Leon+Andrew=15 ⇒L+A=15 ⇒A=15-L ⇒A=15-(13-T) because Leon =13-Ted
A=2+T
Ted+Andrew=14
T+A=14 ( substitute Andrew age from A=2+T)
T+2+T=14
2T=12
<h2>T=12/2=6 (Ted is 6 years old)</h2><h2>A=2+T=2+6=8 ( Andrew is 8 years old)</h2><h2>Leon=13-T=13-6=7 ( Leons is seven years old)</h2>
check: Ted+Leon=13 ⇒ 6+7=13
Leon + Andrew=15 ⇒7+8=15
Andrew+Ted=14 ⇒ 6+8=14
Answer: A. $0.60
Step-by-step explanation:
The prices for which the carpets were sold are
1) 100 square feet for $67
2) 200 square feet for $130
3) 400 square feet for $240
4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes
1) 1 square feet costs 67/100 = $0.67
2) 1 square feet costs 130/200 = $0.65
3) 1 square feet costs 240/400 = $0.6
4) 1 square feet costs 504/800 = $0.63
The unit cost per square foot of carpet for the worst deal is $0.6
