Answer:
Step-by-step explanation:
4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)
5) Cost of top = $9
Cost of 3 top = 9*3 = $27
Cost of skirt = $x
Cost of 3 skirt = 3x
Cost of 3 skirt and 3 top = 3x + 27
Cost of 2 skirt = 2x (as she bought 5 skirts)
Cost of her purchase = Cost of 3skirt &3 top and 2skirt
= (3x + 27) + 2x
= 5x +27
6) Cost of 5 nail polish bottle = 5p
Cost of two lip gloss tube = 2g
Cost of one gift bag = 5p + 2g
Cost of 8 gift bag = 8* ( 5p + 2g)
=8*5p + 8*2g
= 40p + 16g
