Answer:
box of standard strawberries = 80
box of deluxe strawberries = 55
Step-by-step explanation:
Given data:
A box of standard strawberries sells for $7
a box of deluxe strawberries sells for $10.
Total number of sells 135 boxes
total revenue of $1110.
Let box of standard strawberries be x
Let box of deluxe strawberries be y
x + y = 135 <em>(equation 1)</em>
7x + 10y = 1110 <em>(equation 2)</em>
<em>These are now simultaneous equations</em>
<em>From equation 1</em>
y = 135-x <em>(equation 3)</em>
<em>Substituting equation 3 into equation 2</em>
7x + 10(135-x) = 1110
7x + 1350 - 10x = 1110
7x -10x = 1110-1350
-3x = -240
x = 80
<em>Substituting x into equation 3</em>
y = 135 - x
y = 135 -80
y= 55
