A clothing store sells a customer 3 T-shirts and 4 pairs of shorts for $83.

1 answer:

7 0

3t + 4s = $83
4t + 1s = $50 (x 4)

16t + 4s = $200
3t + 4s = $83 (minus them£

13t = $117 (divide by 13)

t = $9

sub t into first equation.

3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14

t = $9
s = $14

Part A

kkurt [141]

Answer:

Part A: A

Part B: A

Step-by-step explanation:

the inequality should be less than or equal to, since we need to find how many are left

now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few

thus, the answer is A

A again is correct, since it represents:c ≤ 56

B represents c ≥ 56

C represents c ≤ –56

D represents c ≥ -56
