Step-by-step explanation:
Simple
We will subtract
21 - 16 = 5
So 5 more students can join the class
[7×(-3)] × (-2)²
= (-21) × 4
= -84

Answer:
I think its C if I’m wrong sorry
Step-by-step explanation:
Answer:
134 sneakers and 66 sandals
Step-by-step explanation:
Sneakers= x, sandals= y
Profit rate:
- sneakers: (10-2)/8= 25%
- sandals: (17-14)/14= 21.4%
Sneakers are more profitable, so it should be maximized.
Cost:
8x+14y≤2000
x+y≤200
if we assume the maximum of 200 shoes stocked, then:
x= 200-y
8(200-y)+14y ≤ 2000
1600 - 8y +14y ≤ 2000
6y≤400
y≤66 and x=134 is the best option
