Answer:
75 boxes of standard varieties and 40 boxes of deluxe varieties.
Step-by-step explanation:
Let x be the number of standard variety and y be the number of the deluxe variety of the strawberry,
∵ Total number of strawberries = 115,
⇒ x + y = 115
⇒ x = 115 - y -----(1),
Total spending amount is $ 700, in which each standard variety costs $ 4 and deluxe variety costs $ 10,
⇒ 4x + 10y = 700 ----(2),
From equation (1),
4(115-y) + 10y = 700
460 - 4y + 10y = 700
460 + 6y = 700
6y = 240
⇒ y = 40
Again from equation (1),
x = 115 - 40 = 75
Hence, there are 75 boxes of standard varieties and 40 boxes of deluxe varieties.
