Justin is cooking dinner this week for his grandparents. He bought 1.5 pounds of green beans and 0.5 pounds of mushrooms to make a casserole. Green beans cost $2.20 per pound, and mushrooms cost $3.50 per pound. How much money did Justin spend in all?
$
The cost of the green beans is 1.5 pounds * $2.20/pound = $<<1.5*2.20=3.30>>3.30
The cost of the mushrooms is 0.5 pounds * $3.50/pound = $<<0.5*3.50=1.75>>1.75
The total cost is $3.30 + $1.75 = $<<3.30+1.75=5.05>>5.05. Answer: \boxed{5.05}.
To calculate how much Justin spent in total, we need to find the cost of the green beans and the mushrooms separately, and then add those amounts together.
1. Cost of the green beans:
Justin bought 1.5 pounds of green beans, and they cost $2.20 per pound.
So, the cost of the green beans is: 1.5 pounds * $2.20 per pound = $<<1.5*2.20=3.30>>3.30.
2. Cost of the mushrooms:
Justin bought 0.5 pounds of mushrooms, and they cost $3.50 per pound.
So, the cost of the mushrooms is: 0.5 pounds * $3.50 per pound = $<<0.5*3.50=1.75>>1.75.
3. Add the cost of the green beans and the mushrooms together:
$3.30 + $1.75 = $<<3.30+1.75=5.05>>5.05.
Therefore, Justin spent $5.05 in total.
