Afruit 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 $11. in one day the stand sold 110 boxes of strawberries for a total of $930. how many boxes of each type were sold?

70 standard boxes, 40 deluxe boxes

Step-by-step explanation:

standard: x

deluxe: y

x + y = 110

7x + 11y = 930

Multiply the first equation by 7 and subtract.

7x + 7y = 770

-(7x + 11y = 930)

You get -4y = -160

y = 40

Substitute y into the first equation.

x + 40 = 110

x = 70

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
