small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames

Can’t get half a box
Answer:15 boxes
we can call guest x
1/3x+5/12x+69=total guests at the wedding
if we multiply 1/3 by 4 we get 4/12. we can add 4/12 to 5/12 to get 9/12 which can be reduces to 3/4. that means the vegetarian guests make up 1/4 of the wedding. if 69 is 1/4, then we have all the information we need to solve this
25% 69 ----- ------ 100% ?
we are solving for the question mark. this is just a diagram. we know 25% of the 100% of the guest and we know that we have 69 of the however many guest. multiply 100 by 69
100x69=6900
now divide 6900 by 25
6900/25=276 guests at the wedding
