Emma buys and sells truck parts. she bought two tires for $35.00 each and later sold them for $65.00 each. she bought three rims for $75.00 each and later sold them for $136.00 each. she bought five headlight covers for $4.00 each and later sold them for 15.00 each. what is emma's total profit?

Emma made a profit of $298.00

Step-by-step explanation:

Emma bought two tires  = $35.00 each

Cost of two tires              =  35 × 2 = $70.00

She bought three rims    = $75.00 each

Cost of three rims            = 75 × 3 = $225.00

She bought five headlight covers  = $4.00 each

Cost of 5 headlight covers   =  5 × 4 = $20.00

Total Cost price of the items = 70 + 225 + 20 =  $315.00

She sold both tires = $65.00 each

                                =  65 × 2 = $130.00

She sold three rims  =  $136.00 each

                                  =  136.00 × 3 = $408.00

She sold 5 headlight covers =  $15.00 each

                                               = 15 × 5 = $75.00

Selling price of all the items =  130 + 408 + 75 = $613.00

Profit = selling price - cost price

P = 613.00 - 315.00 = $298.00

Emma made a profit of $298.00

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
