Answer:
He spend approximately $11.49
Explanation:
Consider the provided information.
The cost of 1 pound tuna salad is $9.99
This can be written as:
1 pound = $9.99
The cost of 0.75 pounds of tuna cost will be:
Multiply both the sides by 0.75
1×0.75 pound = $9.99×0.75
0.75 pound = $7.4925
The cost of 1 pound chicken salad is $7.99
The cost of 0.5 pounds of chicken cost will be:
Multiply both the sides by 0.5
1×0.5 pound = $7.99×0.5
0.5 pound = $3.995
Hence, the total cost is:
$7.4925+$3.995=$11.4875
Hence, he spend approximately $11.49
