• D. $55

Answer 1

The correct option is C $65

Price of 1 scoop for each flavor:

$\text{Vanilla =}\$5$
$\text{Mint-chocolate =}\$8$
$\text{Strawberry =}\$6$
$\text{Butterscotch =}\$12$
$\text{Black currant =}\$9$

Kiara's bill:

$\text{2 scoops of vanilla}=2\times 5=\$10$
$\text{2 scoops of mint-chocolate}=2\times 8=\$16$
$\text{1 scoop of butterscotch}=\$12$

$\text{Kiara's total bill}=\$10+\$16+\$12=\$38$

Diana's order:

$\text{3 scoops of strawberry}=3\times 6=\$18$
$\text{1 scoop of black currant}=\$9$
$\text{Diana's total bill}=\$18+\$9=\$27$

$\text{Total amount spent}=\$38+\$27=\$65$

Thus, Diana spent $65 on her promotion party.
