A fruit stand sells two varieties of strawberries: standard and deluxe. A box of standard strawberries sells for $7, and a box of deluxe strawberries sells for $10. In one day the stand sells 135 boxes of strawberries for a total of $1110. How many boxes of each type were sold

box of standard strawberries = 80

box of deluxe strawberries = 55

Step-by-step explanation:

A box of standard strawberries = $7

A box of deluxe strawberries = $10.

Totalsale of 135 boxes = $1110.

Let box of standard strawberries = X and box of deluxe strawberries = Y

Number of boxes equation:

X + Y = 135

Price of boxes equation:

7X + 10Y = 1110

Solving the Equations simultaneously,

X = 135 - Y  putting into,

7X + 10Y = 1110

7(135 - Y) + 10Y = 1110

945 - 7Y + 10Y = 1110

3Y = 165

Therefore, Y = 55

55 = 135 - X

X = 135 - 55

= 80.

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
