Let $A be the cost of $q of merchandise under plan A and similarly $B under plan B.
A=120+0.80q, B=40+0.90q
When A=B, 120+0.80q=40+0.90q, 80=0.10q, q=80/0.10=$800.
So you would need to buy $800 of merchandise.
A=B=120+640=40+720=$760 for each plan.
1b) 70, 40
1c) 45, 90
1d) 25%
1e) 5%
2a) 360
2b) 180
2c) protractor
2d) compass
2e) diameter
2f) radius
2g) 90
2h) acute
For 1b), the other equal angle would be 70; the remaining angle would be 180-(70+70) = 180-140 = 40.
For 1c), the other equal angle would be 45; the remaining angle would be 180-(45+45) = 180-90 = 90.
For 1d), he saved 50/200; dividing this, we get 0.25; 0.25*100 = 25%.
For 1e), he saved 28/560; dividing this, we get 0.05; 0.05*100 = 5%.

Answer:
15 plates
Step-by-step explanation:
450 divided by 30 = 15, meaning 30 x 15 would be 450 mg. This also means that if the weight of some plates was 450 mg, there would be 15 plates.
