The total money Dana spent in all is $24.75
<h3>Ratio and proportions</h3>
Ratio are written as fractions of two integers. For instance a/b.
Amount spent for grandmother = $13.75
Amount spent on grand father = 4/5 * 13.75
Amount spent on grand father = $11
Take the sum
Total money spent = $13.75 + $11
Total money spent = $24.75
Hence the total money Dana spent in all is $24.75

Answer:
Incremental cost of buying = $2.50
Step-by-step explanation:
Cost per unit;
Direct materials = $10.30
Direct labor = $24.30
Overhead = $16.30
Total Overhead cost = 10.30 + 24.30 + 16.30
= $50.90
Where the item is purchased,
Total cost = $46.88 + (40% × 16.30)
= $46.88 + $6.52
= $53.40
Cost difference = $53.40 - $50.90
= $2.50
There is an incremental cost of buying. This amounts to $2.50
Set a porportion: 60/50=x/20 and solve for x=24
Answer:
3.69 C.
Step-by-step explanation:
if u use the calculator it will have a lot of numbers but to the nearest hundreth it is 68 rounded is 69
The measure of B will be given by:
cos θ= adjacent/hypotenuse
θ=B
adjacent=a=2
hypotenuse=c=√5
thus;
cos B=2/√5
thus
B=arccos 2/√5
B=26.565°~26°
