### Instruction: Every week, Judy goes to the supermarket and buys the following: $5$ carrots at $\$1$ each, $3$ bottles of milk at $\$3$ each, $2$ pineapples at $\$4$ each, $2$ bags of flour at $\$5$ each, and a giant $\$7$ container of ice cream. This week the store has a sale and pineapples are half price. Judy also has a coupon for $\$5$ off any order of $\$25$ or over. How much money does Judy spend on this shopping trip?### Response: I want to find the total amount of money that Judy spends on this shopping trip, after the sale and the coupon are applied.
First, I will add up the prices of all the items that she buys, before the sale and the coupon, to get the original subtotal.
$5$ carrots at $\$1$ each cost $5 \times 1 = \$5$.
$3$ bottles of milk at $\$3$ each cost $3 \times 3 = \$9$.
$2$ pineapples at $\$4$ each cost $2 \times 4 = \$8$.
$2$ bags of flour at $\$5$ each cost $2 \times 5 = \$10$.
And a giant $\$7$ container of ice cream costs $\$7$.
The original subtotal is $5 + 9 + 8 + 10 + 7 = \$39$.
Next, I will apply the sale on pineapples, which are half price.
That means that instead of paying $\$8$ for the $2$ pineapples, Judy only pays $\$4$.
So I will subtract $\$4$ from the original subtotal to get the new subtotal.
The new subtotal is $39 - 4 = \$35$.
Finally, I will apply the coupon for $\$5$ off any order of $\$25$ or over.
Since the new subtotal is over $\$25$, Judy can use the coupon and save $\$5$.
So I will subtract $\$5$ from the new subtotal to get the final total.
The final total is $35 - 5 = \$30$.
Therefore, Judy spends $\$30$ on this shopping trip.
