I don’t know how to do this question

lubasha [3.4K]

let x represent the number of apples and y represent the number of oranges.

TOTAL: x + y = 112

y = 112 - x

PEELED: $\frac{3}{8}x = \frac{1}{2}y$

$(8)\frac{3}{8}x = (8)\frac{1}{2}y$

3x = 4y

3x = 4(112 - x)

3x = 448 - 4x

7x = 448

x = 64

y = 112 - x

= 112 - 64

= 48

a) There are 64 apples and 48 oranges

Peeled apples: $\frac{3}{8}x = \frac{3}{8}(64)$ = 3(8) = 24

Unpeeled apples: 64 - 24 = 40

Unpeeled - Peeled: 40 - 24 - 16

b) there are 16 more unpeeled apples than peeled apples
