Answer:
Step-by-step explanation:
Let
x= Quantity of donuts
y= Quantity of cupcakes
He bought 3 times as many donuts as cupcakes
Donuts=y= 3x
Donuts=0.50 each
Cupcakes=1.00 each
PxQx + PyQy = 10.00
0.50(x) + 1.00(y) = 10.00
0.50x + 1.00(3x)=10.00
0.50x+3.00x=10.00
3.50x=10.00
Divide both sides by 3.50
x=10.00/3.50
=2.86
y=3x
y=3(2.86)
=8.58
Jamal bought 2.86 donuts and 8.58 cupcakes
Check:
PxQx + PyQy = 10.00
0.50(2.86) + 1.00(8.58) = 10.00
1.43 + 8.58=10.00
10.01=10.00
10.01 approximately 10.00
