Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70
Answer:
<em>75 in²</em>
Step-by-step explanation:
Substitute 5 and 3 for a and b in the original expression.
8(a+b)
8(5+3)
Using the rules of PEMDAS, solve the inside of the parentheses first, then multiply accordingly.
8(8)
<u>The final answer is 64.</u>
