Graciela is at the produce market buying fruit. Mangoes cost $0.70 per pound, strawberries cost $1.40 per pound, and guavas cost $5.50 per pound
If Graciela buys 2 pounds of mangoes, half a pound of strawberries, and 3 pounds of guavas, what is the total cost of fruit (ignoring tax)?
OA. $17.60
OB. $19.30
OC. $18.60
D. $41.80

$18.00

Step-by-step explanation:

To find the total cost of fruit, start by calculating the total cost of each type of fruit. To calculate the total cost for a type of fruit, multiply the fruit's cost per pound by the number of pounds purchased.

Calculate the total cost of the mangoes.

$0.80 per pound × 2 pounds = $1.60

Calculate the total cost of the strawberries.

$1.60 per pound × 0.5 pound = $0.80

Calculate the total cost of the guavas.

$5.20 per pound × 3 pounds = $15.60

Now, add these three totals.

$1.60 + $0.80 + $15.60 = $18.00

So, the total cost of the fruit is $18.00.
