a. What is the total cost for a basket of goods that includes 210 gallons of gas, 55 pizzas, 40 6-packs, and 2 textbooks

Explanation:

In the base year, the total cost was:

= (210 * 1.30) + (55 * 3.60) + (40 * 3.90) + (2 * 94)

= 273 + 198 + 156 + 188

= $815

Last year, the total cost was:

= (210 * 1.60) + (55 * 7.65) + (40 * 6.64) + (2 * 221)

= 336 + 420.75 + 265.60 + 442

= $1,464.35

Notice that the total cost increased last year from the base year. This is the effect of inflation. Things get more expensive overtime.

i guess you could put raise the economic balance

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
