Answer:
1) 27.82$
3) 5.6 lbs
Explanation:
I will describe Dried fruit as x
Mixed nuts as y
and Trail mix as z
__________________________
1) Steven buys 2.32 lbs of z and twice as many lbs of
x
1 lb of z = 3.5 $
2.32 lbs of z = ( 3.5 × 2.32 )$
= 8.12 $
Steven bought twice as many lbs of x
So, there are (2.32 × 2) lbs of x
therefore, Steven bought 4.64 lbs of x
1 lb of x = 4.25 $
4.64 lbs of x = (4.25 × 4.64 ) $
x = 19.72 $
Total cost = 19.72 + 8.12 = 27.84 $

3) Mario received 0.4 in change from 20.0$ when he bought z
a) I will subtract 0.4 from 20.0 to first solve the problem
b) 20.0 - 0.4 = 19.6 $
(Mario paid 19.6$ for z)
3.5 $ is paid for l lb of z
19.6 $ is paid for = 1 × 19.6 / 3.5
= 196/35
= 5.6 lbs
Mario bought 5.6 lbs of trail mix.
