Answer:
The first store
Step-by-step explanation:
3sweaters->$44.99
4sweaters->x
x=4×44.99/3 x=$59.98
3sweaters->$52.00
4sweaters->x
x=4×52/3 x=$69.33
first store<second store
59.98<69.33
D + q = 35....d = 35 - q
0.10d + 0.25q = 6.50
0.10(35 - q) + 0.25q = 6.50
3.50 - 0.10q + 0.25q = 6.50
-0.10q + 0.25q = 6.50 - 3.50
0.15q = 3
q = 3 / 0.15
q = 20 <=== 20 quarters
d + q = 35
d + 20 = 35
d = 35 - 20
d = 15 <=== 15 dimes
Answer:
525 ft sq.
Step-by-step explanation:
Variable.
Length = 2w+5
Width = w
2(l+w)=100
2(2w+5+w)=100
2(3w+5)=100
6w+10=100
w=15
l=35
15*35=525
