Answer:
$1.75
Step-by-step explanation:
Total spends on veggies and fruits by Chen = $28.70
Total pints of cut veggies bought = 5
Total pints of cut fruit bought = 7
Let '<em>v</em>' be the cost of each pint of veggies bought and
'<em>f</em>' be the cost of each pint of fruit bought.
Cost for veggies =
Cost of fruit =
Total cost = Cost of veggies + Cost of fruit

Given that f = $2.85
Then v = ?
Putting value of in the above equation and finding the value of v:
So, the price of a pint of veggies, .
If I remember correctly this is how you solve it.
f(x)=8x+6
f(-1)=8(-1)+6
f(-1)=-8+6
f(-1)= -2
