A. Therefore the percentage of decrease he drove this week compared to the last week is 25%

B.Therefore at store A will the cost of blanket be less this week

Step-by-step explanation:

A.

Christopher drove 360 miles this week . Last week he drove 480 miles .

He drove = (480 -360 ) miles = 120 miles less than this week .

Therefore the percentage of decrease he drove this week compared to the last week is= $\frac{120}{480} \times 100$ % =25%.

B.

At store A , a blanket usually costs $50 and blanket the same  at store B usually cost$62. This week , the blanket is on sale At store A for 20% off and at store B for 30% off.

At store A ,

This week, the cost of the blanket  is = $ $50 \times \frac{100-20}{100}$   = $$50 \times \frac{80}{100}$ = $40

At store B

This week, the cost of the blanket  is =$ $62 \times \frac{100-30}{100}$ =$$62 \times \frac{70}{100}$ = $ 43.4

Therefore at store A will the cost of blanket be less this week
