A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10
They have 5 of the Model A and 10 of model B.
Step-by-step explanation:
120/20=6g
50/20=2.5g
170/20=8.5g
for one shortbread ^^
6*50=300g
2.5*50=125g
8.5*50=425g
for 50 shortbread ^^
No it would be $481. 80 because of the 1.5. you ar3 supposed to do 7.30 times 44 and then equals 321.20 so you times that by 1.5
